Step‑by‑Step Instructions for Lazy Lasagna Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) and take a moment to grease a 9×13-inch casserole dish with a little olive oil or cooking spray. This ensures that your Lazy Lasagna Casserole doesn’t stick and comes out easily once baked, ready to serve and enjoy.
Step 2: Cook the Pasta
In a large pot, bring salted water to a rolling boil, then add the uncooked penne pasta. Cook it for one minute less than the package directions—about 7-8 minutes—until it’s al dente. Drain the pasta thoroughly and set it aside, allowing any excess water to escape to avoid a soggy casserole.
Step 3: Brown the Meat Mixture
Heat a large skillet over medium-high heat and drizzle in olive oil. Once hot, add the lean ground beef, chopped onion, garlic powder, Italian seasoning, salt, and black pepper. Sauté everything together for 7-8 minutes, stirring occasionally, until the beef is browned and the onions are soft and translucent, filling your kitchen with that irresistible aroma.
Step 4: Combine Cheese and Sauce
Reduce the heat to medium-low, then stir in the cottage cheese and pasta sauce into the beef mixture. Mix well to create a creamy, savory filling that embodies the essence of the Lazy Lasagna Casserole. Allow this mixture to simmer for a few minutes, enhancing the flavors while you get ready for the next step.
Step 5: Mix in the Pasta
Add the drained penne pasta to the skillet, folding it into the meat and cheese mixture gently until everything is well combined. Ensure the pasta is evenly coated with the sauce for maximum flavor in every single bite of your Lazy Lasagna Casserole, creating a delightful foundation for your dish.
Step 6: Transfer to Casserole Dish
Carefully pour the pasta mixture into the greased casserole dish, spreading it out evenly with a spatula. This step is crucial to ensure even baking, which will give your casserole that perfect bubbly, golden finish when it’s done.
Step 7: Add the Cheese Topping
Sprinkle the shredded mozzarella cheese generously over the top of the assembled Lazy Lasagna Casserole. Make sure to cover the entire surface well; this will create a deliciously gooey top layer that melts beautifully during baking, enhancing the comforting vibe of this dish.
Step 8: Bake to Perfection
Place the casserole in the preheated oven and bake for about 15 minutes, or until the cheese is bubbly and starts to turn golden brown. Keep an eye on it, as the aroma will fill your home, signaling that your Lazy Lasagna Casserole is almost ready to delight your family and friends!
Step 9: Garnish and Serve
Once baked to perfection, remove the casserole from the oven and let it cool for a few minutes. Garnish with freshly chopped basil for a pop of color and freshness before serving. Spoon generous portions onto plates, and witness the smiles as everyone delights in your easy, homemade Lazy Lasagna Casserole!
