Baked Spaghetti Casserole is my family’s favorite comfort food. Layers of pasta, meat sauce, and a creamy cheesy mixture all baked together.

Preheat oven to 350°F. Spray a 9x13-inch baking dish with oil.
Cook pasta according to package instructions.
While pasta cooks, heat olive oil in a large skillet over medium-high heat. Add ground beef and diced onion; cook, breaking up the meat until it's cooked through and onion has softened. Drain excess fat if necessary.
Add garlic to the skillet and cook just 30 seconds or so, until fragrant. Stir full jar of Prego® Traditional Italian Sauce into the skillet; set aside.
When pasta is done cooking, strain and return to the pot it was cooked in. Add butter and Parmesan cheese and toss until the heat from the pasta melts the butter.
In a small bowl, whisk together eggs; pour into the pasta mixture, tossing it so the eggs coat the pasta. Place half of the coated pasta mixture into the prepared baking dish (9x13-inch baking sheet).
Top the pasta on the baking sheet with half of the cottage cheese, half of the meat/sauce mixture, and half of the mozzarella cheese.
Create a second layer with the remaining half of the ingredients.
Cover with aluminum foil and bake in the preheated oven at 350°F for 30 minutes; remove foil and bake another 10 minutes.
Serve hot.
