Lasagna Basics: What Goes into Lasagna

The brilliant thing about lasagna is it’s really hard to mess up. You can swap in your favorite meats, cheeses and veggies and it’ll (probably) turn out fine. To get started though, there are a couple of key components: noodles, cheese, sauce and filling.

Noodles: Lasagna noodles are large and wide, with curly little edges, and you can find them in just about every pasta aisle. With regular lasagna noodles, some recipes will call for you to boil the noodles before assembly, but you can also buy no-boil noodles, which saves time (and there isn’t much of a difference in taste or texture). You can also make lasagna without noodles at all, by swapping in sturdy sliced veggie layers. Eggplant and zucchini make great noodle substitutes in lasagna.

Cheese: Cheese! What would lasagna be without cheese? Definitely not as good. A standard lasagna recipe will usually have ricotta, mozzarella and perhaps a sprinkle of Parmesan cheese. You can also find recipes that use cream cheese, cottage cheese, provolone and other cheese blends.

Sauce: The sauce is what brings everything together, so choose wisely. Most recipes call for one or two 15 oz. jars of pasta sauce. This could be marinara or Alfredo or whatever you like best. As long as you keep the total amount of sauce in the recipe the same and you like the flavor profile, the sky is the limit.

Filling: This is where you can really make it your own. While spinach, beef and Italian sausage are traditional, you can swap in ground chicken or turkey, use a mix of vegetables or even leftover rotisserie chicken. All meat should be fully cooked before assembling. If you’re using frozen vegetables, they should be thawed and drained first so the casserole doesn’t get watery.

Different Types of Lasagna

Classic lasagna is absolutely delicious, but there are so many ways to customize it with unique flavors.

Mexican Lasagna: Using the same noodle layering method, but swapping in flavors like enchilada sauce, taco seasonings, beans and chiles into your lasagna gives it a tasty Mexican twist. Some recipes even use tortillas in place of noodles.

Chicken Lasagna: Chicken lasagna recipes tend to layer noodles and chicken with white sauces like Alfredo sauce in place of the traditional red pasta sauce and add in even more colorful veggies like broccoli, bell peppers and spinach.

Vegetarian Lasagna: Vegetarian lasagna recipes have no rules except for no meat. The sky is the limit when it comes to ingredients—pack your casserole with bright green spinach leaves or replace the noodles with strips of zucchini or eggplant for an even lighter, flavorful taste.

Pizza Lasagna: Pizza and lasagna: The dinner combo you never knew you needed. But once you try this pepperoni-studded spin on lasagna, you may never go back. Load this casserole with more of your favorite pizza toppings like mushrooms, olives and bell peppers.

How to Store Leftover Lasagna

Lasagna makes the best leftovers! There’s a reason people bring lasagna to new parents or new homeowners—it’s so easy to store, freeze and reheat in a pinch.

How to store lasagna in the fridge: First cover the cooled casserole dish with foil or plastic wrap. If you don’t have too much lasagna left, you could also transfer it to another airtight container. Lasagna will keep in the refrigerator for up to 3 to 5 days.

How to store leftover lasagna in the freezer: You can freeze individual portions wrapped in plastic wrap. Once the pieces are frozen solid, move them into a large freezer bag so they take up less space and don’t get freezer burn.

How to reheat lasagna: Use the oven. Sure, you can reheat it in the microwave, but it’s just not the same. If you’ve frozen your lasagna, make sure it is thawed overnight in the fridge before you reheat it. Preheat an oven to 425°F and put the lasagna portion(s) into an oven-safe dish if it isn’t already in one. If your lasagna is looking particularly dry, add a tablespoon or two of water or extra marinara to the pan. Cover the dish with foil and bake for 20 to 30 minutes until hot and bubbly. The internal temperature should read 165°F using a meat thermometer.
