There’s something magical about pulling a bubbling dish of baked mostaccioli out of the oven – that first whiff of garlic, tomato, and melted cheese instantly transports me back to Sunday dinners at my aunt’s house. She’d always make this crowd-pleasing pasta bake for family gatherings, and within minutes, the serving spoon would be scraping the bottom of the casserole dish. What I love most (aside from devouring it) is how effortlessly it comes together – just boil some pasta, mix up a creamy ricotta filling, layer everything with marinara and sausage, then let the oven work its magic. Whether you’re feeding a hungry crowd or meal prepping for the week, this baked mostaccioli recipe never fails to satisfy.

Ingredients for Baked Mostaccioli
Here’s everything you’ll need to make this cheesy, comforting dish – I’ve learned through trial and error that quality ingredients make all the difference! Gather these items before you start:
- 1/2 pound dry mostaccioli (penne or ziti work great too – use what you’ve got!)
- 15 ounces whole milk ricotta cheese (the full-fat version gives the creamiest texture)
- 3 cloves garlic, minced (fresh is best – none of that jarred stuff!)
- 1 small white onion, finely chopped (about 1/2 cup)
- 1 egg (helps bind everything together)
- 1 teaspoon each garlic powder, onion powder, and fine sea salt
- 1/2 teaspoon ground black pepper (freshly cracked if you have it)
- 1/4 cup parmesan cheese, shredded (the good stuff from the refrigerated section)
- 3-4 cups cooked sausage (I use mild Italian, but spicy works too – drain it well!)
- 1 1/2 cups marinara sauce (homemade or your favorite jarred brand)
- 2 cups mozzarella cheese, grated and divided (save 1 cup for that golden top layer)
- Cooking spray (for the baking dish – nobody likes stuck-on cheese!)
See? Nothing too fancy – just good, honest ingredients that come together to make something truly special. Now let’s get cooking!
Equipment You’ll Need
You won’t need any fancy gadgets for this baked mostaccioli – just these kitchen basics:
- 9×13 inch casserole dish (or similar large baking pan)
- Large mixing bowl (big enough to toss all those ingredients together)
- Cooking spray (my secret weapon against stuck-on cheese)
- Wooden spoon (for mixing – silicone works too)
- Cheese grater (if you’re shredding your own mozzarella)
That’s it! Now let’s move on to the fun part – making the most delicious baked mostaccioli you’ve ever tasted.

How to Make Baked Mostaccioli
Alright, let’s get down to business! Making this baked mostaccioli is easier than you think – just follow these simple steps and you’ll have a bubbling, cheesy masterpiece in no time.
Step 1: Prep the Pasta and Oven
First things first – crank that oven to 350°F and give your baking dish a quick spray with cooking oil. Now, boil your mostaccioli (or whatever pasta shape you’re using) in salted water until it’s just al dente – about 1 minute less than the package says. Trust me, nobody wants mushy pasta! Drain it well, then if you’re not using it right away, toss it with a teaspoon of olive oil to prevent sticking. This little trick has saved me from many a pasta clump disaster.
Step 2: Mix the Cheese Filling
In your biggest mixing bowl (I always grab my trusty yellow one for this), plop in the ricotta, minced garlic, chopped onion, egg, all those lovely spices, and the parmesan cheese. Now roll up your sleeves and mix until everything is beautifully combined – no dry pockets of ricotta allowed! The mixture should look creamy and speckled with all those aromatic ingredients. This is where the magic starts happening.
Step 3: Assemble and Bake
Time to bring it all together! Fold the cooked pasta, sausage, marinara sauce, and 1 cup of mozzarella into your ricotta mixture. Watch as everything turns into this glorious, cheesy mess. Pour it into your prepared baking dish and top with the remaining mozzarella – be generous here! Bake uncovered for 25-30 minutes until the cheese is golden and bubbly around the edges. Don’t walk away during the last few minutes – that’s when the cheese goes from perfect to burnt in a heartbeat!
When it comes out of the oven, try to let it rest for 5 minutes before diving in (I know, torture!). This helps the layers set so you get beautiful slices rather than a cheesy landslide. Then grab your fork and prepare for pasta perfection!
Tips for Perfect Baked Mostaccioli
After making this dish more times than I can count (and surviving a few kitchen disasters), here are my hard-earned secrets for baked mostaccioli perfection:
- Drain that sausage well – excess grease makes the dish oily (learned this the messy way!)
- Let it rest 5 minutes after baking – this prevents the “cheese avalanche” when serving
- Taste your marinara first – some brands are saltier than others, so adjust seasoning accordingly
- Undercook the pasta slightly – it keeps cooking in the oven and stays perfectly al dente
Follow these simple tricks, and you’ll have neighbors knocking on your door asking what smells so amazing!
Variations and Substitutions
One of the best things about this baked mostaccioli recipe is how easily you can tweak it to suit your tastes or dietary needs! Here are my favorite variations that still deliver that same comforting goodness:
- Vegetarian version: Skip the sausage and add sautéed mushrooms or spinach instead – just as hearty!
- Gluten-free: Use your favorite GF pasta (I like brown rice penne for its texture)
- Lighter option: Swap in part-skim ricotta and reduced-fat mozzarella – still delicious
- Spicy kick: Use hot Italian sausage or add red pepper flakes to the ricotta mix
The possibilities are endless – make it your own! Just don’t skimp on the cheese… some things are sacred.
Serving and Storing Baked Mostaccioli
Oh, the joy of serving this bubbling, cheesy masterpiece! I always pair my baked mostaccioli with garlic bread (to sop up that delicious sauce) and a crisp green salad – the perfect balance of comfort and freshness. For parties, I’ll sometimes slice it into squares for easy serving, but at home? We dive right in with big spoons!
Leftovers (if you’re lucky enough to have any) keep beautifully. Just cool completely, then cover tightly and refrigerate for up to 3 days. To reheat, pop individual portions in the microwave or warm the whole dish covered with foil at 350°F for about 20 minutes. It also freezes like a dream – wrap well and freeze for up to 2 months. Thaw overnight in the fridge before reheating. Pro tip: Add a sprinkle of fresh mozzarella when reheating for that just-baked look!
Nutritional Information
Now, I’m no nutritionist, but here’s the scoop on what you’re getting in each delicious serving (based on my exact ingredients – yours might vary slightly): about 472 calories, 24g of that good fat, 35g carbs to fuel your day, and a solid 25g protein to keep you satisfied. Remember, these numbers can change depending on the brands you use – that’s just how cooking works! But one thing’s for sure – every bite is packed with flavor and comfort.
FAQs About Baked Mostaccioli
Can I use cottage cheese instead of ricotta?
Absolutely! I’ve done this in a pinch – just blend the cottage cheese first for a smoother texture. The flavor will be slightly tangier, but still delicious. My grandma actually preferred it this way!
How long does baked mostaccioli last frozen?
It freezes beautifully for up to 2 months if wrapped tightly. I always write the date on the foil with a sharpie – because frozen casseroles all look the same after a while! Thaw overnight in the fridge before reheating.
Can I make this vegetarian?
Of course! Skip the sausage and load up on veggies instead. My favorite combo is sautéed mushrooms, zucchini, and spinach. The ricotta keeps it satisfying without the meat.
Why does my cheese topping turn out rubbery?
Ah, the dreaded rubber cheese! Usually means it’s overcooked or you used pre-shredded cheese (those anti-caking agents don’t melt as nicely). Freshly grated mozzarella and keeping an eye on baking time solves this every time.
