Baked Mostaccioli combines Italian sausage, peppers, garlic, onions, and marinara, all blanketed in mozzarella and provolone cheese. It is the ultimate easy comfort food meal, family-friendly and guaranteed to please!
This baked pasta is a hearty meal by itself, but I like to serve it with triple cheese garlic bread and Italian salad for a complete, company-worthy meal.

The Ultimate Baked Mostaccioli
This is not your lunch ladies’ mostaccioli—or your wedding day mostaccioli. This delicious baked mostaccioli contains layers of fresh Italian sausage, sweet onions, minced garlic, and marinara. It is then topped with Parmesan and mozzarella cheese.
Baked Mostaccioli can be prepped in advance, loaded in the refrigerator, and baked at the optimum time. We are one pasta-loving family. Pasta is so easy, comforting, and darn delicious every time. If you like this recipe, try chicken tortellini alfredo, spaghetti and meatballs, beefaroni, and cheese stuffed manicotti.

How to make Baked Mostaccioli
First, bring a large pot of salted water to boil. Cook your mostaccioli noodles al dente according to package instructions and drain well. Meanwhile, brown the sausage in a large ovenproof skillet over medium heat. When about halfway browned, add the green pepper and onions. Cook until the peppers and onions are soft. Reduce the heat and add the minced garlic and Italian seasoning, cooking for one minute. Remove the pan from the heat and drain any excess grease.

Next, stir in the cooked sausage mixture, cooked pasta, and marinara. You can also transfer everything to a casserole dish. Then, top the pasta mixture with an even layer of grated Parmesan Cheese and shredded mozzarella cheese. Bake in the oven for about 25 minutes or until the cheese melts and lightly browns. If desired, garnish with chopped fresh Italian parsley.

Recipe Tips
- Cook the mostaccioli al dente, which means still somewhat firm. It will be baked with the sausage, veggies, and sauce. Don’t overcook it.
- Use good quality Italian sausage. Most butcher shops make their own, which tastes much better than processed sausage with all the preservatives.
- Grate and shred your cheese fresh from the block. That way, you will not have preservatives, added enzymes, and cellulose.

Frequently Asked Questions
Substitute ground beef, ground turkey, or ground pork for the Italian sausage.
Other tubular pasta types to use include penne, ziti, or rigatoni.

Great looking recipe! I’m curious though: in the description it says to add onions and peppers when sausage is halfway brown, but in the step by step instructions it says remove sausage when done then add them. Which appears to work better?
Beth Pierce
Honestly, either way will work.
