Homestyle Baked Spaghetti

This cheesy baked spaghetti is one of my favorite freezer meals. It’s super simple and perfect for busy weeknights. I also love chicken broccoli rice casserole, green chile enchiladas, Mexican lasagna and chicken pot pie.

If you’re looking for an easy and delicious comfort meal, this baked spaghetti (also known as spaghetti casserole) is perfect for you. It has 4 different kinds of cheese inside and is coated in a flavorful pasta sauce. It’s similar to lasagna and my favorite million dollar spaghetti but with a few small tweaks. Talk about delicious!

This is the perfect meal for family gatherings or to bring someone when they need a meal. We also make this occasionally when we have guests over. It makes a lot!

My whole family loves this delicious baked pasta dish and requests it again and again. It’s definitely one of my kid’s favorite meals. We love serving this spaghetti with a big salad and homemade garlic bread.

How to Make Baked Spaghetti

Step 1: Brown the ground beef 

Add hamburger to a large pan and heat over medium-high heat. Break apart with a spoon, then add in onions. Cook until they become soft, about 3 to 5 minutes. Then add garlic and cook for 1 additional minute. Cook meat until browned. S&P to taste, then add in Italian seasoning.

Step 2: Add sauce and simmer 

Add in spaghetti sauce and let simmer uncovered for about 10 minutes.

Step 3: Cook the noodles 

Cook spaghetti noodles about 6 minutes, or until al dente. Do not overcook. Reserve 1 cup of water for pasta sauce and then drain. Add up to 1/2-1 cup of the water to the red sauce.

Step 4: Mix in remaining ingredients 

Once noodles are drained, add in the cream cheese and toss together. Once it begins to melt, add in the cottage cheese, 1/2 cup mozzarella cheese and 1/4 cup grated parmesan cheese. Then toss together with the sauce. Then press into a greased 9×13″ pan.

Step 5: Bake in oven 

Add remaining mozzarella cheese, fresh basil and parmesan to the top of the casserole if desired. Then bake in the oven at 350°F for 30-40 minutes.

Can I Freeze Spaghetti Casserole?

This recipe makes a lot, so most of the time I will freeze half of the spaghetti (before baking) to save for a busy day. Follow the simple instructions below to freeze and then thaw.

  • To freeze: Do not bake. Combine the sauce and noodles and then allow to cool completely. Once cooled, add to a freezer container and top with remaining cheese. Label with the date (I love these freezer labels), then store in the freezer for up to 3 months.
  • To thaw: Remove from freezer and place in refrigerator. Let thaw overnight, then cook in the oven at 350°F for 30-40 minutes.
