Instructions
Step 1: Get Your Oven Ready

- Add the Mostaccioli and cook according to the package directions until it’s al dente – just firm enough to hold up in the oven.
- Drain and set aside.
Step 3: Sauté the Veggies
- While the pasta is cooking, heat the olive oil in a large skillet over medium heat.
- Add the chopped onion and minced garlic, and sauté until the onion is soft and translucent – about 3-4 minutes.
- Enjoy that amazing aroma!
Step 4: Cook the Meat
- Add the ground beef or Italian sausage to the skillet, breaking it up with a spoon.
- Cook until it’s browned and no longer pink, stirring occasionally.
- Drain any excess fat to keep the dish light and tasty.
Step 5: Add the Sauce
- Stir in the marinara sauce, letting it simmer for a few minutes to blend all those wonderful flavors.
- This step is key for a rich, flavorful sauce.
Step 6: Combine with Pasta
- In a large mixing bowl or the pot used for the pasta, combine the cooked Mostaccioli with the sauce mixture.
- Add half of the shredded mozzarella and half of the grated Parmesan.
- Toss until every piece of pasta is coated in the cheesy, saucy mixture.
Step 7: Assemble for Baking
- Pour the pasta mixture into a 9″x13″ baking dish.
- Sprinkle the remaining mozzarella and Parmesan cheese on top.
- Finish with a dash of Italian seasoning to boost the flavor.
Step 8: Bake to Perfection
- Place the baking dish in the preheated oven and bake uncovered for about 25 minutes, or until the cheese is melted, bubbly, and beginning to turn golden brown.
Step 9: Let it Rest and Serve
- Remove from the oven and let it sit for a few minutes to set.
- Garnish with fresh basil, if desired, for a touch of color and extra flavor.
- Serve hot and enjoy!
FAQs
Can I make this recipe ahead of time?
Yes! You can assemble the Mostaccioli up to the baking step and store it in the refrigerator for up to 24 hours. When you’re ready to bake, just add a few extra minutes to the baking time.
What are some good substitutes for Mostaccioli pasta?
If you can’t find Mostaccioli, you can use any tubular pasta like penne or rigatoni. These types hold the sauce well and work perfectly for baking.

Can I just put the uncooked pasta in with the sauce and let it cook that way? Saves me a step haha, Sandra what do you think?
That might make the pasta too mushy. It’s better to cook it separate first.
sautéing veggies is like frying them right
Tried adding a little smoked paprika to the meat, and it was a game-changer! Thanks for the baseline recipe, Sandra.
The steps are easy to follow, but I think it lacked a bit of seasoning. Could use more herbs maybe.
step 10 – order pizza instead, got it
Does it matter what kind of tomatoes I use for the sauce?
Actually, if you use whole grain pasta, it could be a bit healthier. Not sure if everyone is into that though.
great tip! always looking for ways to make meals healthier.
love making this for my grandkids they eat it up every time
could’ve just bought a ready meal and saved an hour, just saying
There’s joy in cooking from scratch. It’s not just about saving time.
