Ingredients You’ll Need

1 lb plant-based ground beef: Adds heartiness; substitutes for traditional ground beef while being vegetarian-friendly. Brands like Beyond Meat work great.
1 24-oz tub whole milk cottage cheese: Provides creaminess that binds everything together; you can substitute ricotta cheese for a richer texture.
2 tbsp cornstarch: Acts as a thickening agent for the cottage cheese to help create that creamy layer; can be swapped with arrowroot powder if gluten-free is needed.
1 24-oz jar marinara: The convenient base sauce; look for a brand with no added sugars for a healthier option.
1 cup water: Helps to thin out the marinara; a splash of vegetable broth can add more flavor.
3 cloves garlic, minced: Infuses the dish with aromatic flavor; use garlic powder in a pinch, but fresh is best.
1 tsp Italian seasoning: Brings classic Italian flavors; make your own mix or use any store-bought blend.
12 oz oven-ready lasagna noodles: Eliminates the need for pre-cooking; make sure they are truly oven-ready to ensure even cooking.
8 oz mozzarella, grated from block: Freshly shredded melts better than pre-shredded; this adds that gooey, cheesy top layer.

How to Make Lazy Lasagna Casserole

Preheat the Oven: Set your oven to 375°F (190°C), so it’s nice and hot when your casserole is ready to bake.
Cook “Beef”: In a large sauté pan, drizzle a splash of oil and crumble 1 lb plant-based ground beef. Cook until browned, about 6-8 minutes, stirring occasionally.
Blend: While the “beef” cooks, combine 1 24-oz tub whole milk cottage cheese and 2 tbsp cornstarch in a blender. Blend until smooth and creamy.
Prepare the Sauce: In a 9×13 inch casserole dish, dump in the cooked “beef,” 1 24-oz jar marinara, 1 cup water (swirl it around the marinara jar to extract leftover sauce), 3 cloves minced garlic, and 1 tsp Italian seasoning. Stir well to combine.
Layer the Noodles: Roughly break 12 oz oven-ready lasagna noodles into 2 to 3 inch pieces. Stir them into the sauce mixture to coat them thoroughly, then gently press them down into an even layer in the casserole dish.
Add Cheese: Pour the blended cottage cheese mixture evenly over the noodles. Grate 8 oz of mozzarella and sprinkle it generously on top of the dish.
Bake: Cover with aluminum foil tightly and bake for 45 to 50 minutes, or until the pasta is al dente and the sauce is bubbling at the edges. Uncover and bake for an additional 15 minutes, until the cheese is lightly browned and the pasta is tender.

Storing & Reheating

Leftovers can be stored at room temperature for up to two hours, otherwise move them to the refrigerator in an airtight container, where they will last for about 3-4 days. If you want to save it for later, freeze your Lazy Lasagna Casserole in a freezer-safe dish for up to 3 months. When you’re ready to enjoy, reheat in the oven at 350°F (175°C) for about 30-35 minutes or until heated through. Be aware that freezing might slightly alter the texture, but a splash of fresh marinara can refresh its flavor.

Chef’s Helpful Tips

Avoid overcooking the plant-based beef by keeping a close eye on it while sautéing; golden is good, but brown and crispy isn’t needful here.
To achieve a creamy texture in your cottage cheese layer, blend it thoroughly to avoid any lumps, ensuring a smooth top layer.
For a little extra zest, consider adding some red pepper flakes or fresh herbs like basil before baking.
If the casserole seems dry after baking, add a little extra water mixed with marinara before the final bake to keep things moist.
Make it ahead by assembling the casserole the day before and storing it covered in the fridge, then bake it fresh when ready.

Lazy Lasagna Casserole is a delightful dish that marries convenience with taste. It’s rich, satisfying, and utterly delightful. You get all the cozy feels without fussing over layers and sauces. So go ahead, dive into this comforting classic and maybe even customize it to make it your own with spices or additional vegetables. Enjoy the warm, cheesy goodness!

Recipe FAQs

Can I make this casserole gluten-free?

Absolutely! You can substitute regular oven-ready lasagna noodles with gluten-free options. Be sure to read the package instructions as some gluten-free pasta may require adjustments in cooking time.

How can I add more veggies?

Feel free to layer in your favorite vegetables to the sauce, like chopped spinach, zucchini, or bell peppers. You could sauté them with the plant-based beef for more flavor and added nutrition.

Can I use a different type of cheese?

Certainly! If you’re not a fan of cottage cheese, ricotta or cream cheese can work wonderfully as a substitute. Just make sure to maintain the creamy texture!

How does this casserole freeze?

This Lazy Lasagna Casserole freezes well! To do so, let it cool to room temperature first, then wrap tightly with aluminum foil or transfer to a freezer-safe container. Don’t forget to label it with the date!
