Baked Spaghetti is a favorite casserole around here!  A quick zesty meat sauce is combined with tomatoes and spaghetti and topped with cheese.  This spaghetti casserole is baked in the oven until hot and bubbly.

Just like stuffed shells, this easy recipe is perfect served with  crusty bread, homemade Garlic Butter and a Caesar Salad.

Easy Baked Spaghetti

This easy baked spaghetti casserole is a family favorite that is loaded with flavor!  We love Italian flavors from Easy Meatballs to a simple bruschetta and this cheesy casserole is no exception!

While Million Dollar Spaghetti Casserole contains a lot of cheese in the spaghetti mixture (like cream cheese, cottage cheese or ricotta), this recipe is simple has pasta and sauce with a little bit of cheese on top.

How to Make Baked Spaghetti

Baked Spaghetti Casserole is easy to make, simply prepare the meat sauce, toss with spaghetti and bake until bubbly. The prep can be done then night before and then baked before serving making this baked spaghetti the perfect potluck dish!

  1. Brown beef and onions. Add veggies and tomato sauce and simmer.
  2. Stir in spaghetti and place in a dish.
  3. Top with cheese and bake!

The cheese on top gets golden and crusty making for amazing flavor! Make sure your spaghetti is cooked al dente as the noodles do cook a bit more in the oven and you don’t want them to get mushy.

One great thing about this recipe is that you can add whatever you like to the sauce. If you don’t like green pepper, skip it and add diced mushrooms or zucchini.  You can easily adjust this to your liking and add more or less sauce if you’d prefer.

How Long to Bake Spaghetti

Since the pasta and the sauce are warm when I put this dish together, it usually takes about 25 minutes or so to bake in the oven.  If you prep it ahead of time and refrigerate, it’ll take a bit longer.  Remove it from the fridge about 30 minutes before baking and bake about 35 minutes or until hot in the centre.

Do You Cover Baked Spaghetti

I never cover baked spaghetti because the  crusty cheese on top is my favorite part!  Covering this dish also makes it steam which can overcook the spaghetti.

  1. I want to make this soon but need clarification about the 14.5 oz diced tomatoes. Do I use the whole can with juice? Or do I need to drain it?

  2. This was great. I’ve made it before so was looking for a guideline but I followed this in all ways except adding green peppers. I would make it again. I also like using mild Italian sausage with it and that way I don’t have to add the seasonings. But I used ground beef many times. It works either way.5 stars

  3. Is there anyway I could make this vegetarian? Should I simply remove the meat or would that affect the texure too much?

  4. We loved the casserole tonight! I would love to split a recipe and freeze to keep on hand for a busy day or to give a friend. How should you freeze this (baked or uncooked)?
    Thank you,
    Betsy5 stars

    1. Hi Betsy, I would freeze uncooked then when you’re ready to eat it, just thaw completely and bake in the oven for the same time/temp. So glad your family loves this dish!

  5. So good? My partner ate all 8 servings the same night so I didn’t get to have any! Boy, did it smell great, though!5 stars

  6. I had a baby 3 weeks ago and our neighbor brought this over for dinner. Oh. My. Goodness. It was the BEST baked spaghetti I’ve ever had & I have tried lots of different recipes myself, & that others have made. My 2 & 5 year old tore it up as well. I had to ask her for the recipe so I could pin it myself.5 stars

    1. Congratulation on your new little one Charis. That makes us so happy to hear! Glad the whole family enjoyed this one.

      1. Hi so for “Fresh parmesan cheese ” do you mean grated like you would find in a plastic container aka Kraft or do you mean freshly shredded?

  7. When my husband asked “what’s for dinner? I answered” Baked Spaghetti”, he responded with “I don’t think I’ll like that.”. He was.right he didn’t like it …..he loved it. He had 2 generous helping and complimented me on how yummy it was. If you think you may not like it, try it , you won’t be disappointed.5 stars

  8. Hello,
    I don’t usually leave reviews but looking for something to use up a pound of mild Italian sausage (ground), I tried this out. I did not have several ingredients (green peppers, fresh parsley, mozzarella or Parmesan cheese). It still came out great, topped with just a little bit of a Mexican shredded cheese blend. I did also top it with an easy homemade Bechamel sauce. If you’ve ever had the vegetarian lasagna on Carnival Cruise lines, it’s their recipe (I halved it). Fantastic! Thank You For Sharing.

    Bechamel Recipe
    Ingredients: 1/2 c. butter, 1/2 c. AP flour, 4 c. milk, 1 whole peeled onion, 4 garlic cloves, 1 bay leaf, salt/pepper/ground nutmeg to taste

    Procedure: In medium saucepan, melt butter over medium-high heat; stir in flour. Cook 4 to 5 minutes; do not allow it to color. Remove from heat. In medium saucepan heat milk, onion, garlic and bay leaf over medium heat. When milk comes to a boil remove onion, garlic and bay leaf. Slowly add hot milk to butter-flour mixture, stirring constantly. Reduce heat to low and simmer for 20 minutes or until smooth and thickened. Stirring with a wire whisk or wooden spoon. Season to taste with salt, white pepper and nutmeg.

  9. Hi Holly,
    Let me preface this by saying I rarely leave reviews on recipes because let’s be honest, a lot of them do not turn out like one would hope. This, however, turned out amazing!! I was looking for an inexpensive way to feed a bunch of 17 year old boys (my son has his DnD group over every Friday), work through my pantry staples (I must have 20 cans of tomato sauce to make who knows what) and not end up with a sink full of dishes (ugh, I hate dishes) when I came across your baked spaghetti recipe. I followed your directions using canned tomato sauce, pork sausage, whole grain spaghetti and a little more cheese and garlic, we love our garlic!! Served with garlic, parmesan Texas toast. Every single one of those boys cleaned their plates (even the one that swore he hates onions)! In fact, my dinner guest raved about it as well! I will be making this again, using up the other 17 cans of tomato sauce?!! Huge hit, thank you very much! Looking forward to trying more of your recipes! BTW, this fit perfectly in a foil lasagne pan lightly oiled with olive oil, so hardly any cleanup as well!5 stars

    1. So happy to hear this recipe was such a hit Tryn! Definitely a good one to keep in the cooking repertoire when feeding that many hungry teenagers!!

  10. I find most baked spaghetti recipes to be too dry for my own taste so I only added half the spaghetti . I also only added one clove of garlic because I’m not a huge garlic lover. These changes made it absolutely delicious to us and will be our go to baked spaghetti recipe from now on!5 stars

  11. I made this last evening, it was soooo good! My husband loved it! I threw in some diced white mushrooms with all the other ingredients. The left-overs were frozen and I cannot wait to make something, else. I am new to the site and I am up early looking for tonight’s main meal! Thank you!5 stars

  12. Fantastic!! Thank you for such easy delicious recipes. Just one question, is that parsley that you’ve garnished the baked spaghetti with?5 stars

  13. This is an awesome recipe. But I didn’t put the can of cut up tomatoes in it just excellent Silver Palate marinara sauce plus 1 tablespoon of sugar made it awesome. I use ground venison also so so good. Also Italian Mozzarella to die for.5 stars
