It was one of those chilly Sunday evenings where everyone seemed to linger in the kitchen a little longer, drawn in by the warmth of the oven and the promise of something comforting. I wanted a meal that could feed a crowd, make great leftovers, and fill the house with that unmistakable scent of home-cooked love.
I had spaghetti, I had cheese, and I had some leftover meat sauce from the night before—so I layered it all into a dish, popped it in the oven, and what came out was nothing short of magical. Bubbly cheese, golden edges, and saucy pasta in every bite.
That’s how this Baked Spaghetti Casserole came to be. A twist on a classic, but one that feels just a little more special—without any extra fuss.
Short Description

Key Ingredients
- 12 oz spaghetti, cooked and drained
- 1 lb ground beef (or Italian sausage)
- 1 small onion, diced
- 2 cloves garlic, minced
- 1 jar (24 oz) marinara or spaghetti sauce
- 1 tsp Italian seasoning
- Salt and pepper, to taste
- 2 eggs
- ½ cup grated Parmesan cheese
- 1½ cups cottage cheese or ricotta
- 2 cups shredded mozzarella cheese
- Fresh basil or parsley for garnish (optional)
Tools Needed
- Large skillet
- Saucepan or pot
- Mixing bowls
- 9×13 inch baking dish
- Spatula or wooden spoon
- Foil for covering
Cooking Instructions
Step 1: Preheat and prep
Preheat your oven to 375°F (190°C). Lightly grease your 9×13 baking dish.
Step 2: Cook the meat sauce
In a large skillet over medium heat, cook the ground beef and diced onion until browned. Add garlic and cook for 1 minute. Drain any excess fat. Stir in the marinara sauce and Italian seasoning. Simmer for 10 minutes.
Step 3: Prep the spaghetti layer
In a large bowl, whisk the eggs and stir in the cooked spaghetti, Parmesan, salt, and pepper. Mix well to coat the noodles.
Step 4: Layer the casserole
Spread half of the spaghetti mixture in the baking dish. Top with all of the cottage cheese or ricotta, then half of the meat sauce. Add the remaining spaghetti, followed by the rest of the meat sauce. Finish with mozzarella cheese on top.
Step 5: Bake
Cover with foil and bake for 30 minutes. Remove foil and bake another 10–15 minutes until the cheese is golden and bubbly.
Step 6: Let rest & serve
Let the casserole rest for 10 minutes before slicing. Garnish with chopped basil or parsley, if desired.
