Lasagna, that magnificent symphony of pasta, cheese, sauce, and meat (or vegetables), is a dish that often tastes even better the next day. But the quest to recapture that oven-baked perfection in the microwave can be fraught with peril. All too often, we end up with a dry, rubbery, and disappointing version of its former glory. Fear not, lasagna lovers! This comprehensive guide will equip you with the knowledge and techniques to reheat lasagna in the microwave while preserving its delicious moisture and texture.
Understanding the Microwave Reheating Challenge
The microwave oven, a marvel of modern convenience, operates by using microwave radiation to excite water molecules in food, generating heat. While efficient, this process can be uneven and, critically, tends to evaporate moisture quickly. This is the primary culprit behind dried-out lasagna. The key to successful microwave reheating is to mitigate this moisture loss and ensure even heating throughout the dish.
Why Does Lasagna Dry Out in the Microwave?
Think of lasagna as a carefully constructed ecosystem. The layers of pasta, cheese, sauce, and fillings all contribute to its overall moisture content and texture. Microwaving disrupts this balance. The microwave energy targets the water within these components, causing it to steam and escape. This is especially problematic for the exposed edges and top layer of the lasagna, which are most susceptible to drying out.
Furthermore, uneven heating is a common issue. The outer edges of the lasagna tend to heat up much faster than the center, leading to overcooked, dry edges and a still-cool interior. This unevenness exacerbates the moisture loss problem, as the hotter areas release more steam.
Essential Techniques for Moist Microwave Lasagna
Reheating lasagna in the microwave requires a strategic approach that prioritizes moisture retention and even heating. Here are some tried-and-true methods to achieve lasagna reheating success:
The Power of Moisture: Adding External Liquids
One of the most effective ways to combat dryness is to introduce additional moisture during the reheating process. This can be achieved in several ways:
Adding Water: Perhaps the simplest approach is to add a small amount of water directly to the lasagna. Place the lasagna slice or portion on a microwave-safe plate. Then, add about a tablespoon of water to the bottom of the plate, around the lasagna. Be careful not to pour the water directly onto the lasagna, as this can make the top layer soggy. The water will create steam as it heats, helping to keep the lasagna moist.
Using Sauce: Another excellent option is to spoon a small amount of marinara sauce over the top of the lasagna before microwaving. This not only adds moisture but also enhances the flavor. Ensure the sauce is evenly distributed to prevent some areas from drying out more than others. You can even use a bit of leftover lasagna sauce if you have it on hand.
Covering with a Damp Paper Towel: Placing a damp paper towel over the lasagna is a classic microwave reheating trick. The damp towel acts as a barrier, trapping steam and preventing moisture from escaping. Ensure the paper towel is thoroughly damp but not dripping wet. This method is particularly effective for preventing the top layer of the lasagna from drying out.
Controlling the Heat: Low and Slow Wins the Race
High-powered microwaving is the enemy of moist lasagna. Instead of blasting the lasagna on high, opt for lower power settings and longer reheating times. This allows the lasagna to heat more evenly and reduces the risk of moisture evaporation.
Lower Power Settings: Most microwaves have power settings ranging from 10% to 100%. When reheating lasagna, aim for a power setting of 50% to 70%. This will significantly reduce the rate at which the lasagna heats, allowing the moisture to be retained.
Incremental Heating: Instead of setting the microwave for a long period of time, reheat the lasagna in short bursts. Microwave for 1-2 minutes at a time, then check the temperature and moisture level. Continue microwaving in short intervals until the lasagna is heated through. This allows you to monitor the progress and prevent overcooking.
The Importance of Covering: Trapping the Steam
Covering the lasagna while microwaving is crucial for trapping steam and preventing moisture loss. You can use a microwave-safe lid, plastic wrap, or even an inverted microwave-safe plate.
Microwave-Safe Lids: If you have a microwave-safe lid that fits over your plate or dish, this is an ideal option. Lids effectively trap steam and promote even heating.
Plastic Wrap: If you don’t have a lid, plastic wrap can be used as a substitute. However, it’s essential to vent the plastic wrap by poking a few holes in it with a fork or knife. This will prevent the plastic wrap from bursting due to the steam buildup. Make sure the plastic wrap is microwave-safe.
Inverted Plate: An inverted microwave-safe plate can also be used as a cover. Simply place the plate upside down over the lasagna, creating a dome that traps steam.
Choosing the Right Container: Optimizing Heat Distribution
The type of container you use can also affect the reheating process. Microwave-safe glass or ceramic dishes are generally preferred over plastic containers, as they tend to heat more evenly.
Glass and Ceramic Dishes: These materials are excellent for microwave cooking because they distribute heat evenly and don’t leach chemicals into the food. Ensure the dish is specifically labeled as microwave-safe.
Avoid Metal: Never use metal containers or foil in the microwave, as they can cause sparks and damage the microwave.
Step-by-Step Guide to Microwave Lasagna Reheating Perfection
Now that we’ve covered the essential techniques, let’s put them all together in a step-by-step guide to reheating lasagna in the microwave without drying it out:
-
Prepare the Lasagna: Place the lasagna slice or portion on a microwave-safe plate or dish.
-
Add Moisture: Add about a tablespoon of water to the bottom of the plate, around the lasagna, or spoon a small amount of marinara sauce over the top.
-
Cover the Lasagna: Cover the plate with a damp paper towel, a microwave-safe lid, or vented plastic wrap.
-
Microwave at Reduced Power: Microwave on 50% to 70% power for 1-2 minutes.
-
Check and Rotate: Carefully remove the lasagna from the microwave. Check the internal temperature and moisture level. Rotate the plate 180 degrees to promote even heating.
-
Continue Heating in Increments: Continue microwaving in 30-second to 1-minute intervals, checking and rotating each time, until the lasagna is heated through. The internal temperature should reach 165°F (74°C).
-
Let it Rest: Once heated through, let the lasagna rest for a minute or two before serving. This allows the heat to distribute evenly and the flavors to meld.
Addressing Common Lasagna Reheating Problems
Even with the best techniques, you might encounter some common problems when reheating lasagna in the microwave. Here’s how to address them:
Dry Edges
If the edges of the lasagna are drying out, try adding a small amount of water or sauce specifically to the edges before microwaving. You can also wrap the edges with damp paper towels to protect them.
Cold Center
If the center of the lasagna is still cold after reheating, continue microwaving in short intervals, checking the temperature each time. Make sure to rotate the plate to promote even heating. If the edges are already getting too dry, consider cutting the lasagna into smaller pieces to help it heat more evenly.
Rubbery Texture
A rubbery texture is usually a sign of overcooking. To avoid this, use lower power settings and reheat the lasagna in short bursts. Adding moisture can also help to prevent the lasagna from becoming rubbery.
Tips for Enhancing Reheated Lasagna
Reheating lasagna doesn’t have to be a compromise. Here are some tips to elevate your reheated lasagna experience:
Fresh Herbs
Sprinkling fresh herbs, such as basil or parsley, over the reheated lasagna can add a burst of freshness and flavor.
A Touch of Cheese
Adding a sprinkle of freshly grated Parmesan or mozzarella cheese to the top of the lasagna before serving can add a delicious cheesy touch.
A Side Salad
Serving the reheated lasagna with a fresh side salad can provide a welcome contrast in textures and flavors. A simple green salad with a vinaigrette dressing is a classic pairing.
Beyond the Microwave: Alternative Reheating Methods
While this guide focuses on microwave reheating, it’s worth noting that there are other methods available. Each has its own pros and cons:
Oven Reheating
Reheating lasagna in the oven is generally considered the best way to preserve its texture and flavor. Preheat the oven to 350°F (175°C). Cover the lasagna with foil and bake for 20-30 minutes, or until heated through. Remove the foil for the last 5-10 minutes to crisp up the top layer.
Skillet Reheating
For individual portions, reheating in a skillet can be a quick and effective option. Add a small amount of oil or butter to a skillet over medium heat. Place the lasagna in the skillet and cook for 5-7 minutes per side, or until heated through.

Why does lasagna often dry out when reheated in the microwave?
Microwaves heat food unevenly by exciting water molecules. This process can cause the water within the lasagna to evaporate rapidly, leading to dryness, especially at the edges and corners. The prolonged microwave exposure needed to adequately heat the center of a thick piece of lasagna exacerbates this moisture loss, resulting in a less appealing texture compared to the original, freshly baked dish.
Overheating, coupled with the open-air environment inside the microwave, contributes significantly to the drying effect. Without a protective barrier or added moisture, the lasagna’s surface becomes exposed to the drying action of the microwaves. Essentially, the microwave is essentially boiling the water out of the lasagna rather than gently warming it.
What’s the best way to prevent lasagna from drying out when microwaving?
The key to preventing dryness lies in retaining moisture during the reheating process. This can be achieved by adding a small amount of water or sauce to the lasagna before microwaving. Covering the lasagna with a microwave-safe lid or plastic wrap (with a small vent) will trap the steam and prevent it from escaping, keeping the lasagna moist.
Another crucial step is to microwave in short intervals at reduced power. Instead of blasting the lasagna on high, use 50% power and microwave in 1-minute intervals, checking the temperature and adding more water or sauce if needed. This allows for more even heating and prevents overcooking, which contributes to dryness.
Should I add water or sauce when reheating lasagna? How much?
Whether to add water or sauce depends on the lasagna’s current moisture content. If the lasagna seems already somewhat moist, a tablespoon or two of water should suffice. However, if it appears dry, especially if the sauce has been absorbed, adding a couple of tablespoons of extra sauce will be more beneficial.
The goal is not to drown the lasagna, but to provide enough moisture to generate steam during microwaving. For individual slices, a teaspoon of water or sauce might be enough. Start with a small amount and assess the results after the first minute of microwaving. You can always add more if needed.
What kind of container is best for reheating lasagna in the microwave?
A microwave-safe container is crucial. Avoid metal containers, as they can spark and damage your microwave. Glass or specifically labeled microwave-safe plastic containers are ideal. The shape of the container also matters; a shallow, wide container allows for more even heating than a deep, narrow one.
Choosing a container with a tight-fitting lid is highly recommended. If a lid isn’t available, microwave-safe plastic wrap can be used as a substitute, but ensure you vent it slightly to allow steam to escape. This prevents pressure buildup and potential explosions.
What microwave power setting is recommended for reheating lasagna?
Using a lower power setting is essential for preventing the lasagna from drying out. A setting of 50% power is generally recommended. This allows the lasagna to heat more evenly and slowly, reducing the risk of overcooking the edges while the center remains cold.
Microwaving at a lower power also helps the moisture within the lasagna to redistribute, rather than evaporating rapidly. Check the lasagna frequently and continue microwaving in short intervals until it’s heated through. Adjust the power or time slightly based on your microwave’s performance.
How long should I microwave lasagna for reheating?
The exact reheating time depends on the size of the portion, the power of your microwave, and the lasagna’s initial temperature. As a general guideline, start with 1-2 minutes on 50% power for a single slice of lasagna. Check the temperature and continue microwaving in 30-second intervals until it’s heated through.
For larger portions, increase the initial time to 3-4 minutes and check frequently. It’s better to underheat and add more time than to overheat and dry out the lasagna. Remember to let the lasagna rest for a minute or two after microwaving to allow the heat to distribute evenly.
How can I tell when the lasagna is properly reheated?
The best way to determine if the lasagna is properly reheated is to check its internal temperature. Use a food thermometer to ensure the center reaches at least 165°F (74°C). If you don’t have a food thermometer, you can also test the temperature by inserting a fork or knife into the center.
The lasagna should be hot and steaming throughout. Ensure that there are no cold spots, especially in the center. If any areas remain cold, continue microwaving in short intervals until the entire portion is heated evenly. Be careful not to overcook it during this final stage.
