Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Spaghetti: Use standard spaghetti for that classic texture; whole wheat is a great alternative if you prefer something healthier.

Marinara Sauce: A good quality jarred sauce makes life easier; homemade is fantastic if you have time to spare.
Onion and Garlic: Fresh onion and garlic add depth; sauté them until aromatic for the best flavor.
Bell Peppers: Use colorful bell peppers to brighten up the dish; they add sweetness and crunch.
Cheese Blend: A mix of mozzarella and cheddar creates that gooey, melty topping everyone loves.

How to Make spaghetti casserole
Prep Your Ingredients: Start by preheating your oven to 350°F (175°C). While it’s heating up, chop your onions, garlic, and bell peppers finely—this ensures they cook evenly.
Cook the Spaghetti: In a large pot of salted boiling water, cook the spaghetti according to package instructions until al dente. Drain it well but save a cup of pasta water just in case!
Sauté Your Veggies: In a large skillet over medium heat, add olive oil and sauté onions, garlic, and bell peppers until they soften—about 5 minutes—bringing out their wonderful aromas.
Add Ground Beef: Toss in the ground beef with some salt and pepper. Cook until browned completely while breaking it apart—around 7-10 minutes should do.
Add Marinara Sauce: Stir in your marinara sauce along with any reserved pasta water if needed; let it simmer gently while mixing everything together—this brings all those flavors together beautifully.
Layer Your Casserole: In a large baking dish, layer half of your spaghetti followed by half of the meat mixture. Top with half of your cheese blend. Repeat these layers once more before finishing with remaining cheese on top.
Bake It Up: Cover your baking dish with foil and bake for about 20 minutes. Remove the foil afterward and bake an additional 10-15 minutes until cheese is bubbly and golden brown—the smell will drive you wild!
Now you’ve got a scrumptious spaghetti casserole that’s ready to steal hearts (and stomachs) at any gathering!
