How to make baked spaghetti

4. Cook about 6-8 minutes, stirring frequently breaking up the ground beef into crumbles until cooked through.
5. Add the garlic to the skillet and mix. Saute for about 1 minute, just until fragrant. Be sure not to burn the garlic.

Substitutions and additions for spaghetti bake
Ground beef - You can substitute the ground beef with Italian sausage, ground turkey, ground sausage, or even ground tofu for a vegetarian version. You want this to be a hearty meat sauce, so use one that holds up to the marinara.
Green Pepper - you can add chopped green pepper to the onions when sautéing the sauce. This will not only add flavor, but it will bulk it up with veggies. The bell pepper can be added with the onions and softened.
Cremini Mushrooms - Baby Bella or cremini mushrooms would go great in this recipe. You can add them into the onions when sautéing for the sauce.
Cream cheese - you can replace the cream cheese with part-skim ricotta cheese if you prefer. I find that cream cheese gives a much better texture and flavor than ricotta cheese, but both work well.
Avocado oil - you can substitute the avocado oil with olive oil or any other neutral-tasting oil.
Red pepper flakes - you can add red pepper flakes to the meat mixture to add a little bit of spice.
Spaghetti pasta - you can use standard spaghetti or thin spaghetti noodles, both work well.

tips for making oven-baked spaghetti
- If you don't use lean ground beef, be sure to drain it before adding the marinara sauce. Otherwise, your baked spaghetti will be greasy.
- When it comes to the marinara sauce, use your favorite. Whether that's a bottled sauce, a basic tomato sauce, a classic marinara pasta sauce, or a homemade sauce, use the one you like most.
- You can use a 13×9-inch or 3-quart baking dish.
- It's not required, but I recommend using part-skim mozzarella cheese that's been freshly grated. Pre-shredded cheese has an anti-caking agent that prevents it from melting as well.
It's easy to make baked spaghetti vegetarian. Just omit the ground beef. Sauté the onions and garlic, add the marinara, and continue with the recipe as written.

Can cheesy baked spaghetti be frozen?
Yes, baked spaghetti can be frozen. You can freeze it in individual servings or as a whole casserole. It's one of my favorite freezer meals.
Allow the casserole to cool completely. Cover and store in a freezer-safe, airtight container for up to 6 months.
How to store and reheat leftover baked spaghetti
To store leftover baked spaghetti, allow it to cool completely. Place it in an airtight container in the refrigerator for up to 3 days.
I find that it's even better the next day when all of the flavors have had a chance to combine even more.
The best way to reheat a pasta bake is in the oven. Place it in an oven-safe dish, cover it with a lid or aluminum foil, and heat it in a 350ºF oven until heated through.
You can also use a microwave. Place it on a microwave-safe dish, cover loosely with a moist paper towel, and heat in 1-minute increments until heated through.
