How to Make Baked Rigatoni Fra Diavolo with Sausage and Zucchini Recipe
Step 1: Prep and Preheat
Start by heating your oven to 350°F (175°C). Grab a generous 9×13-inch baking dish and give it a quick spray with nonstick cooking spray – this will stop all the cheesy pasta goodness from sticking later on. It’s a small prep step but makes cleanup so much easier!
Step 2: Cook the Rigatoni
Bring a large pot of well-salted water to a lively boil, then add your rigatoni. Cook for about 6 to 7 minutes until just al dente – you want it tender but still with a bit of bite to hold up in the oven. Drain the pasta and toss it back into the pot to keep it warm.
Step 3: Sauté the Zucchini
In a wide skillet, heat 1/4 cup of olive oil over medium heat. Add the zucchini rounds and cook them until golden brown on both sides, about 6 minutes total. This step caramelizes the zucchini, bringing out their natural sweetness. Once done, remove them and set aside.
Step 4: Brown the Sausage
Using the same skillet, add the Italian sausage and cook it until it’s beautifully browned and cooked through, about 5 to 7 minutes. Browning the meat gives it a rich, savory depth that will build the sauce’s flavor. Remove the sausage and set aside as well.
Step 5: Build the Sauce Base
Pour out any excess grease from the skillet for a leaner sauce, then add the remaining olive oil. Toss in the diced onion and sauté until soft and translucent, which should take about 8 minutes. Stir in the garlic and crushed red pepper flakes—cook for just a minute to release their wonderful aromas without burning.
Step 6: Add Tomatoes and Seasonings
Next, stir in the tomato paste followed by the crushed tomatoes with basil for that vibrant red sauce. Pour in the white wine or chicken broth to add depth and loosen up the sauce a bit. Season with fresh basil, mint, salt, and black pepper, giving everything a good stir. Let this simmer gently to marry all the flavors together.
Step 7: Combine Sausage and Zucchini with Sauce
Return the browned Italian sausage and golden zucchini to the skillet, mixing well to coat them fully with the spicy fra diavolo sauce. This blending of textures and flavors is what makes this baked rigatoni dish truly sing.
Step 8: Assemble and Bake
Pour the cooked rigatoni into your prepared baking dish. Pour the sausage, zucchini, and sauce mixture evenly over the pasta and mix gently to combine. Then, top everything with half of the shredded mozzarella and scatter the mozzarella cubes on top for a perfect cheese pull as it melts. Bake the dish for 30 minutes until the cheese is bubbling and delightfully golden.
Step 9: Serve with Parmesan
Once baked, take the dish out and sprinkle the top generously with Parmesan cheese. This final addition offers a savory, nutty contrast that is just irresistible. Serve the pasta warm and watch everyone dive in happily!

Freezing
This baked pasta freezes wonderfully. Just cover it tightly with plastic wrap and foil or store in a freezer-safe container. Freeze for up to 2 months. When you’re ready to enjoy, thaw overnight in the refrigerator before reheating.
Reheating

FAQs
Can I use ground beef instead of Italian sausage?
Absolutely! Ground beef or even ground turkey can be great substitutes. Just add some Italian seasoning to keep the robust flavor that sausage typically provides.
What if I don’t have white wine for the sauce?
No worries! Chicken broth is a perfect substitute and still adds that needed liquid and subtle flavor complexity to the sauce.
How spicy is this Baked Rigatoni Fra Diavolo with Sausage and Zucchini Recipe?
The crushed red pepper flakes provide a nice moderate heat that you can adjust to your liking—use less if you prefer milder or more if you love extra spice.
Can I make this dish vegetarian?
Yes! Simply omit the sausage and boost the veggies—adding mushrooms or eggplant are excellent choices that keep the dish hearty and delicious.
Is it important to use fresh herbs?
Fresh basil and mint brighten this dish and add a fresh finish that dried herbs can’t quite match. If you don’t have fresh, dried herbs can work in a pinch but use sparingly to avoid overpowering the sauce.
