Gluten Free Sheet Pan Lasagna

If you love lasagna but don't love the time it takes to layer a traditional casserole, this gluten free sheet pan lasagna is about to become a new favorite. It has all the cheesy, saucy layers you expect from classic lasagna, but it's baked on a sheet pan for a foolproof family dinner!

Why You'll Love This Gluten Free Sheet Pan Lasagna

Traditional lasagna can feel like a project. You have to boil the noodles, prepare the sauce, carefully layer everything in a casserole dish, and then wait for it to bake.

This easy gluten free lasagna recipe is perfect for busy weeknights, family dinners, or anytime you're craving comfort food without spending hours in the kitchen. The edges get deliciously crispy and golden while the center stays saucy, cheesy, and tender.

Best of all, this recipe is easy to customize with your favorite gluten free lasagna noodles, sauce, vegetables, and cheeses.

This sheet pan lasagna recipe simplifies the process.

Instead of baking lasagna in a deep casserole dish, the ingredients are spread across a rimmed sheet pan. This gives you more crispy edges and a higher ratio of cheesy, browned noodles to the soft center.

It's also a great option if you're looking for an easy gluten free dinner recipe that the whole family will enjoy!

Here's why this Gluten Free Lasagna recipe works:

• It's made with no boil gluten free lasagna noodles.
• Everything bakes on one pan.
• You get extra crispy, cheesy edges.
• It's easy to customize with your favorite fillings.
• It's perfect to prep ahead for a weeknight gluten free dinner.
• Leftovers reheat well for lunch the next day.

Ingredients You'll Need

Gluten free lasagna noodles: Use your favorite gluten free lasagna noodles. Oven-ready noodles work especially well for this recipe because they don't need to be boiled first.

Marinara sauce: Use a gluten free marinara sauce that you enjoy. Always check the label if you're cooking for someone with Celiac disease, since ingredients and manufacturing practices can vary by brand.

Ricotta cheese: Ricotta creates the creamy layer that makes lasagna so good.

Frozen chopped spinach: thawed and squeezed very dry.

Mozzarella cheese: Shredded mozzarella melts over the top and gives the lasagna its classic cheesy finish.

Parmesan cheese: A little Parmesan adds extra flavor and helps the top become golden and bubbly.

Italian seasoning: Italian seasoning adds lots of flavor without requiring a long list of ingredients.

Garlic Powder: Garlic gives the lasagna even more flavor.

How to Make Gluten Free Sheet Pan Lasagna

Start by preheating your oven to 400°F. Lightly grease a 13 x 18-inch rimmed sheet pan with olive oil or nonstick cooking spray.

If you're using regular gluten free lasagna noodles rather than oven-ready noodles, cook them according to the package directions. Drain and set aside.

Prepare the spinach. Thaw the frozen spinach and squeeze out as much excess moisture as possible. This is important because too much liquid can make the lasagna watery.

Make the ricotta mixture. In a medium bowl, combine the ricotta cheese, squeezed spinach, ¼ cup Parmesan cheese, Italian seasoning, garlic powder, salt, and black pepper. Stir until well combined.

Now it's time to assemble your gluten free sheet pan lasagna!

Start Layering. Spread a thin layer of meat sauce over the bottom of the prepared sheet pan. Arrange a layer of gluten free lasagna noodles over the sauce, breaking them as needed so they fit across the pan.

Add the filling. Spread or spoon some of the spinach and ricotta mixture over the noodles. Add another layer of marinara sauce and sprinkle with mozzarella cheese.

Repeat the layers. Continue layering the noodles, spinach-ricotta mixture, marinara sauce, and mozzarella until you've used the ingredients. Finish with a layer of marinara sauce, the remaining mozzarella, and Parmesan cheese.

Bake. Cover the sheet pan tightly with aluminum foil and bake for 20-25 minutes. Remove the foil and continue baking for another 5-10 minutes, or until the noodles are tender and the cheese is melted and bubbly.

Rest and Serve. Allow the lasagna to rest for about 10 minutes before slicing into square and serving.

Tips for Making the Best Gluten Free Lasagna

Use a rimmed sheet pan

A rimmed baking sheet is important because it keeps the sauce and melted cheese from spilling over the sides. A standard half-sheet pan works well.

Don't skimp on the sauce

Gluten free noodles can sometimes absorb more moisture than traditional pasta, so make sure each layer has enough sauce. This helps prevent dry lasagna.

Let it rest before slicing

It's tempting to cut into the lasagna immediately, but giving it about 10 minutes to rest helps the layers set. You'll get much cleaner slices.

Get those crispy edges

One of my favorite things about making lasagna on a sheet pan is all the crispy edges. Spread the ingredients close to the edges of the pan so you get plenty of those browned, cheesy pieces.

Easy Variations

This gluten free lasagna recipe is easy to change based on what you have in your kitchen.

For a vegetarian version, skip the meat!

Want more protein? Use Italian sausage instead of ground beef or combine the two.

For a lighter option, use part-skim ricotta and mozzarella and add extra vegetables to the layers.

If you're looking for a dairy free lasagna recipe as well as gluten free, use your favorite dairy-free ricotta and dairy-free mozzarella alternatives.

How to Store Leftover Lasagna

Store leftover gluten free sheet pan lasagna in an airtight container in the refrigerator for up to 3-4 days.

You can reheat individual portions in the microwave, but for the best texture, reheat them in the oven or air fryer. This helps bring back some of those delicious crispy edges.

You can also freeze individual portions for an easy gluten free freezer meal. Allow the lasagna to cool completely before wrapping portions tightly and placing them in a freezer-safe container.
