Ingredients You’ll Need
What I adore about this Hearty Spinach and Sausage Pasta Bake is how the most unfussy ingredients work together to create a meal that tastes like a little celebration. Each part of this recipe brings something special to the table, from protein-packed sausage to creamy ricotta and a kiss of spice.
- Penne Pasta: Its ridges perfectly capture all the saucy, cheesy goodness for maximum flavor in every forkful.
- Italian Sausage (casings removed): Adds a rich and savory depth that’s simply irresistible; choose sweet or spicy based on your preference.
- Onion (diced): This aromatic base sweetens and rounds out the sauce beautifully.
- Garlic (minced): Essential for a rich, authentic Italian flavor; fresh is always best.
- Fresh Spinach (roughly chopped): Brings gorgeous color and a nutritious boost—plus it melts right into the dish.
- Marinara Sauce: Use your favorite jarred or homemade marinara to tie everything together with tangy, herby notes.
- Ricotta Cheese: Lends a creamy, mellow layer that makes every bite luscious.
- Shredded Mozzarella Cheese: The ooey-gooey cheese pull on top is a must-have finishing touch.
- Grated Parmesan Cheese: Offers a salty, savory layer of flavor right at the end.
- Red Pepper Flakes (optional): For those who love a gentle heat, a sprinkle of these is magic.
- Salt and Black Pepper: Season to your liking—don’t skip this for a well-rounded taste!
- Olive Oil: A quick sauté starts the flavor party and brings everything together.
How to Make Hearty Spinach and Sausage Pasta Bake
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil and cook the penne pasta according to the package instructions, just until al dente. You want it slightly firm, since it’ll finish cooking in the oven. Drain thoroughly and set aside—it’s the sturdy base that holds up all that sumptuous sauce and cheese to come.
Step 2: Sauté the Onion and Garlic
In a large skillet, heat up the olive oil over medium heat. Toss in your diced onion and let it cook until translucent, which will take about 3 to 4 minutes. Give it a quick stir, then add the minced garlic and let that sizzle for a minute more. The aroma alone will have everyone peeking into the kitchen.
Step 3: Brown the Sausage
Add the Italian sausage to the skillet, breaking it apart with a spoon or spatula. Cook until it’s browned and cooked through, ensuring the sausage’s savory juices flavor your aromatics. If there’s a lot of excess fat, feel free to drain some off, but be sure not to lose that flavor.
Step 4: Wilt the Spinach
Add the chopped fresh spinach right into the pan with your sausage mixture. Stir occasionally until it wilts down, turning vibrantly green in just a minute or two. This step sneaks in veggies without sacrificing any heartiness.
Step 5: Combine Everything Together
Turn off the heat and move the skillet’s contents into a very large mixing bowl. Add your cooked penne, marinara sauce, and ricotta cheese. Sprinkle in those red pepper flakes, plus salt and black pepper, then give everything a big, thorough mix. Every noodle should be coated, every sausage bite cloaked in saucy, cheesy bliss.
Step 6: Assemble the Bake
Spoon the pasta mixture into a greased 9×13-inch baking dish, spreading it out evenly. Generously sprinkle mozzarella and Parmesan cheese over the top to create that gorgeous, melty layer everyone fights over at the table.
Step 7: Bake to Perfection
Preheat your oven to 375°F (190°C) if you haven’t already, and bake the casserole uncovered for 25 to 30 minutes until the cheese is melted, golden, and bubbling all around the edges. Let it rest for about 5 minutes before serving—this will help the Hearty Spinach and Sausage Pasta Bake set up just enough for perfect slices.
How to Serve Hearty Spinach and Sausage Pasta Bake
Garnishes
A final flourish is half the fun! Brighten up each slice with a scatter of fresh basil ribbons, a dusting of extra Parmesan, or a few twists of cracked black pepper just before serving. These little touches boost both the flavor and the homemade vibe.
Side Dishes
Pair your Hearty Spinach and Sausage Pasta Bake with a crisp green salad tossed in a tangy Italian vinaigrette, some garlicky roasted vegetables, or—my personal favorite—a basket of warm, crusty bread to mop up any extra sauce. It’s a meal that really loves good company.
Creative Ways to Present
Want to dazzle? Serve individual portions in mini cast iron skillets or ramekins for a dinner party-worthy twist. Or, pack leftovers into lunchbox-sized thermoses for a comforting work or school lunch. However you plate it, this dish looks and tastes spectacular.
Make Ahead and Storage
Storing Leftovers
Leftover Hearty Spinach and Sausage Pasta Bake keeps beautifully! Transfer cooled portions to airtight containers and refrigerate for up to four days. The flavors deepen overnight, making leftovers an irresistible reward.
Freezing
This pasta bake is a freezer superstar. You can wrap the whole (unbaked) casserole tightly in foil and freeze for up to two months. When ready, thaw in the refrigerator overnight, then bake as usual, adding a few extra minutes to ensure it’s heated through.
Reheating
To reheat, simply cover a portion with foil and warm in a 350°F (175°C) oven until bubbly—usually 15 to 20 minutes. For a speedier option, zap single slices in the microwave in 30-second bursts until hot. If the pasta looks a little dry, add a splash of marinara or a drizzle of olive oil before reheating.
FAQs
Can I use a different type Main Dish, Casserole
Absolutely! While penne is traditional for the Hearty Spinach and Sausage Pasta Bake, any short, sturdy pasta shape like rigatoni, ziti, or even rotini will hold up well and soak up the sauce.

Yes, you can assemble the whole casserole (without baking), cover it tightly, and store it in the fridge up to 24 hours in advance. Pop it into the oven whenever you’re ready for a hands-off dinner.
What kind of marinara sauce works best?
Any high-quality jarred or homemade marinara sauce will shine. If you like things garlicky or herby, look for those versions to add extra personality to your Hearty Spinach and Sausage Pasta Bake.

Of course! Just use your favorite gluten-free pasta and double-check that all your other ingredients, especially the sausage and marinara, are gluten-free. The result will be every bit as comforting.
