Hearty Italian Sausage Penne Casserole
Ingredients
Equipment
Method
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- Bring a large pot of salted water to a rolling boil. Add the penne pasta and cook according to package directions until al dente (firm to the bite). Drain well and set aside.
- While the pasta cooks, heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the bulk Italian sausage, breaking it apart with a spoon as it cooks. Brown the sausage evenly, then drain any excess fat.
- Add the chopped onion to the skillet with the sausage and cook until softened, about 5-7 minutes. Stir in the minced garlic and cook for another minute until fragrant.
- Stir in the tomato paste and cook for 1 minute to deepen its flavor. Pour in the crushed tomatoes and chicken or vegetable broth. Add the dried oregano, dried basil, red pepper flakes (if using), 1 tsp salt, and 1/2 tsp black pepper. Bring the sauce to a simmer, then reduce the heat to low and let it cook for 10-15 minutes, stirring occasionally, allowing the flavors to meld.
- In a medium bowl, combine the ricotta cheese, 1/2 cup of the shredded mozzarella, 1/4 cup of the grated Parmesan, the large egg, chopped fresh parsley, 1/4 tsp salt, and 1/8 tsp black pepper. Mix thoroughly until all ingredients are well combined.
- Add the drained penne pasta to the skillet with the sausage and tomato sauce. Toss gently to ensure the pasta is evenly coated with the sauce.
- Spread half of the pasta mixture evenly into the prepared 9×13 inch baking dish.
- Dollop half of the ricotta cheese mixture over the pasta layer.
- Sprinkle with the remaining 1/2 cup shredded mozzarella and 1/4 cup grated Parmesan cheese.
- Repeat the layers: add the remaining pasta mixture, then dollop the remaining ricotta mixture on top.
- Cover the baking dish loosely with aluminum foil and bake for 20 minutes.
- Remove the foil and continue baking for another 10-15 minutes, or until the casserole is bubbly around the edges and the cheese topping is melted and lightly golden brown.
- Let the casserole stand for 5-10 minutes before serving to allow it to set and cool slightly. Garnish with extra fresh parsley if desired.
Notes
Pro Tips for Making This Italian Sausage Penne Casserole
Making a delicious casserole like this Italian sausage penne casserole is all about those little touches that elevate it from good to truly unforgettable. I’ve learned a few tricks over the years that I’m excited to share with you, ensuring your dish turns out perfectly every time.
When browning your Italian sausage, break it up well with a wooden spoon so you don’t end up with large chunks. This allows the flavor to distribute evenly throughout the sauce.
My Secret Trick: I always reserve a little bit of the pasta cooking water before draining. If my sauce ever seems too thick after simmering, a splash of that starchy water can thin it out beautifully while helping the sauce cling to the penne. It’s a simple way to achieve that perfect consistency!
Don’t be shy with the herbs! Dried oregano and basil really shine in this dish. I like to rub them between my palms before adding them to the sauce; it helps release their essential oils for a more vibrant flavor.
When preparing your ricotta mixture, ensure all ingredients are well combined. This prevents any pockets of unseasoned cheese and ensures a creamy, consistent layer throughout your italian sausage penne casserole.
Fun Variations for Italian Sausage Penne Casserole
One of the greatest joys of cooking is getting to play with flavors and making a recipe truly your own! This Italian sausage penne casserole is wonderfully adaptable, and I encourage you to get creative. My sister always asks me to add a little something extra, and these ideas are born from those playful kitchen experiments.
Veggie Boost
For an extra layer of goodness and color, consider stirring in some finely diced bell peppers, zucchini, or even a handful of spinach into the sauce as it simmers. They cook down beautifully and add a lovely freshness without overpowering the robust flavors of the italian sausage penne casserole.
Spice It Up
If you love a little heat, increase the red pepper flakes or add a pinch of cayenne pepper to the sauce. You could also try using a hot Italian sausage instead of mild for an extra kick that really warms you from the inside out.
Cheesy Swaps
While the mozzarella, ricotta, and Parmesan blend is classic, feel free to experiment with other cheeses! Provolone adds a sharp, tangy note, or a smoky Gouda could introduce an unexpected depth. A friend loves when I sprinkle some smoked paprika into the ricotta mixture for a hint of warmth.
What to Serve With Italian Sausage Penne Casserole
This delightful Italian sausage penne casserole is such a complete meal on its own, but a few simple accompaniments can truly elevate the experience. When I serve a hearty dish like this, I always think about balancing the richness with something fresh and light.
I love serving it alongside a crisp, green salad with a light vinaigrette. The freshness cuts through the richness of the italian sausage penne casserole beautifully and adds a lovely texture. A simple mix of mixed greens, cherry tomatoes, and cucumber is often all you need.
Another wonderful pairing is a basket of warm, crusty garlic bread. It’s perfect for soaking up any extra sauce and adds that comforting, familiar touch to the meal. My mom always had a loaf ready to go with any pasta dish.
For a slightly more elegant touch, consider a side of lightly steamed green beans or asparagus, seasoned simply with a little olive oil, salt, and pepper. Their vibrant color and tender-crisp texture make for a lovely contrast.
How to Store Italian Sausage Penne Casserole

Keeping your leftover Italian sausage penne casserole tasting as delicious as it did fresh from the oven is wonderfully simple with a few smart storage tips. There’s nothing worse than dry leftovers, so here’s how I keep mine perfect.
Refrigerator Storage
Once cooled completely, transfer any leftover italian sausage penne casserole to an airtight container. It will keep beautifully in the refrigerator for 3-4 days. This makes it perfect for delicious lunches or quick dinners throughout the week.
Freezer Friendly
Yes, this casserole freezes like a dream! After cooling, divide the casserole into individual portions or a larger freezer-safe dish, wrap it tightly with plastic wrap, and then cover with foil. It will stay fresh in the freezer for up to 2-3 months.
Reheating Instructions
To reheat from the fridge, simply warm individual portions in the microwave until heated through, or cover a larger dish with foil and bake at 350°F (175°C) until bubbly. If reheating from frozen, thaw overnight in the fridge first, then reheat as above. My personal tip? A sprinkle of fresh parsley or a dusting of extra Parmesan after reheating brings it back to life!
Nutritional Benefits
This delicious casserole, while a hearty comfort food, offers some wonderful nutritional benefits. The lean Italian sausage provides a good source of protein, while the crushed tomatoes are packed with antioxidants like lycopene. Combined with the fiber from the penne pasta, this italian sausage penne casserole is a treat that’s both satisfying and nourishing, embodying my approach of enjoying wholesome ingredients with a personal touch.
FAQs
Faq 1
Can I prepare the Italian sausage penne casserole ahead of time?
Absolutely! You can assemble the entire italian sausage penne casserole up to a day in advance. Just cover it tightly and store it in the refrigerator. When you’re ready to bake, let it sit at room temperature for about 30 minutes before baking as directed.
Faq 2
What kind of penne pasta should I use?
I always recommend using good quality penne pasta, preferably durum wheat. Rigatoni or ziti would also work beautifully if you don’t have penne. Cook it to al dente, as it will continue to cook in the oven when baking this italian sausage penne casserole.
Faq 3
Can I make this casserole vegetarian?
Yes, you certainly can! Simply omit the Italian sausage and use plant-based ground “meat” crumbles or a mixture of finely diced mushrooms and lentils as your savory base. Be sure to use vegetable broth to make your vegetarian italian sausage penne casserole.
Faq 4
Why is my casserole watery?
A watery italian sausage penne casserole can often be caused by under-reducing the sauce, or not draining the pasta well enough. Ensure your crushed tomatoes simmer sufficiently to thicken, and always drain your cooked pasta thoroughly before adding it to the mixture.
