Step‑by‑Step Instructions for Lazy Lasagna Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grease a 9x13-inch casserole dish with cooking spray or olive oil. This will help the Lazy Lasagna Casserole release easily after baking and ensure a deliciously golden finish.

Step 2: Cook the Pasta
Bring a large pot of salted water to a boil and add 2 cups of uncooked penne pasta. Cook the pasta for 1 minute less than the package instructions to ensure it doesn’t become mushy during baking. Once cooked, drain the pasta thoroughly and set it aside to cool slightly, allowing it to absorb flavor later.

Step 3: Brown the Meat
In a large skillet over medium-high heat, add 1 tablespoon of olive oil. Once hot, add 1 pound of lean ground beef along with the chopped onion. Sprinkle in 1 tablespoon of garlic powder, 2 teaspoons of Italian seasoning, and salt and black pepper to taste. Cook the mixture for 7-8 minutes, stirring occasionally, until the beef is browned and the onions are translucent.

Step 4: Mix in Cheese and Sauce
After the beef is cooked, stir in 1 cup of cottage cheese and the entire 24-ounce jar of pasta sauce. Mix everything together until well combined, creating a rich and savory filling for your Lazy Lasagna Casserole that will envelop every bite of pasta.

Step 5: Combine Ingredients
Next, take the cooked and drained penne pasta and add it directly to the beef and cheese mixture in the skillet. Stir gently to ensure all ingredients are evenly mixed, so each piece of pasta is coated in the savory sauce. This will create a beautifully integrated casserole base.

Step 6: Assemble the Casserole
Transfer the combined mixture from the skillet into the greased casserole dish. Spread it out evenly, ensuring that the layers are uniform. This will help the casserole cook evenly in the oven and also make it more visually appealing when serving.

Step 7: Top with Cheese
Sprinkle 8 ounces of shredded mozzarella cheese generously over the top of your casserole. The cheese will melt and create a deliciously gooey layer that pulls nicely apart, giving that classic lasagna look and feel to your Lazy Lasagna Casserole.

Step 8: Bake to Perfection
Place the casserole in the preheated oven and bake for about 15 minutes. You’ll know it’s ready when the cheese is bubbling and turns a light golden brown. This visual cue indicates that all flavors have melded beautifully together.

Step 9: Garnish and Serve
Once the Lazy Lasagna Casserole is baked to perfection, remove it from the oven and let it cool for a few minutes. To finish, garnish with fresh chopped basil for a burst of color and flavor. Serve warm, and enjoy this comforting, high-protein dish with loved ones!
