Notes on ingredients and swaps
This One Pot Penne Pasta Recipe calls for smoked sausage. If you prefer a milder flavor, choose a turkey-based smoked sausage. For vegetarian eaters, consider a plant-based smoked sausage alternative and use vegetable broth instead of chicken stock. Monterey Jack brings creamy meltiness; if unavailable, young mozzarella or a mild cheddar will work. The jarred roasted red peppers contribute both sweetness and a roasted depth—keep the jarred liquid in the pot so the pasta absorbs that flavor as it cooks.
Equipment
- Large heavy-bottomed skillet or wide pot with a lid (at least 12-inch skillet or a 4-quart pot)
- Spoon or spatula for stirring
- Measuring cups
- Knife and cutting board
Prep ahead
- Slice the smoked sausage and refrigerate until ready to use.
- Dice the onion, mince the garlic, and slice the mushrooms to save time while cooking.
- Shred the cheeses and keep them chilled until needed to make melting easier and prevent clumping.
Step-by-step instructions
The following directions have been rewritten for clarity and flow while keeping the original order. Follow each step closely to get the best texture and flavor for this One Pot Penne Pasta Recipe.
- Heat a large heavy-bottomed skillet or wide pot over medium heat. Add the sliced smoked sausage and cook, stirring occasionally, until the edges are slightly browned and the sausage has released some fat, about 5 to 7 minutes. This browning step builds savory depth for the dish.
- Add the diced onion to the pan with the sausage. Cook, stirring every minute or so, until the onion becomes translucent and soft, about 3 to 4 minutes. This will mellow the onion’s sharpness and create a sweet base flavor.
- Stir in the minced garlic and the sliced mushrooms. Cook for another 2 to 3 minutes, until the garlic becomes fragrant and the mushrooms begin to soften and release their liquid. Keep stirring so nothing sticks or burns.
- Pour in the 2 cups of chicken stock or broth and add the entire 10-ounce jar of roasted red peppers with their juices. Break larger pepper pieces into smaller strips with your spoon so they distribute evenly. Scrape up any browned bits from the bottom of the pan to incorporate that flavor into the liquid.
- Add the uncooked penne pasta to the pot, ensuring the pasta is mostly submerged in the liquid. Bring the mixture to a gentle boil over medium-high heat. Once boiling, reduce the heat to medium-low so the pot maintains a steady simmer. Cover with a lid and cook, stirring every 4 to 5 minutes to prevent sticking and to help the pasta cook evenly, until the penne is al dente—usually about 10 to 12 minutes depending on the brand.
- When the pasta is tender and most of the liquid has been absorbed or thickened into a sauce, remove the pot from the heat. Immediately stir in the 2 cups of Monterey Jack cheese and the 1/2 cup of Parmesan cheese. Mix vigorously until the cheeses melt into a smooth, creamy sauce that coats the pasta.
- Fold in the 2 cups of fresh spinach. The residual heat will wilt the spinach quickly; if you prefer it more tender, return the pot to very low heat for 30 to 60 seconds while stirring until the leaves are fully wilted. Taste and adjust seasoning with salt and pepper if needed.
- Let the pasta rest for 2 minutes to allow the sauce to thicken slightly. Serve hot, garnishing with extra Parmesan if desired. Enjoy this rich, comforting One Pot Penne Pasta Recipe straight from the pot or plated for guests.
Tips for success
- Use a wide pot or skillet so the pasta lays mostly flat for even cooking. Crowded pans can lead to unevenly cooked pasta.
- Stir occasionally during simmering to prevent the pasta from sticking to the bottom and to ensure the starches distribute into the sauce.
- If the liquid evaporates before the pasta is tender, add a splash more chicken stock, 1/4 cup at a time, until the pasta finishes cooking.
- For a creamier finish, reserve a couple of tablespoons of the shredded Monterey Jack to sprinkle over each serving.
- To brighten the dish, squeeze a little lemon juice over individual servings or add a handful of chopped fresh parsley on top.
Variations and add-ins
This One Pot Penne Pasta Recipe is a flexible canvas. Here are a few ideas to change up the flavor profile without extra fuss:
- Spicy: Add 1/4 to 1/2 teaspoon crushed red pepper flakes when you add the garlic.
- Vegetable-forward: Increase the mushrooms to 2 cups and add 1 cup chopped zucchini for extra vegetables.
- Herby: Stir in a teaspoon of dried Italian seasoning during the simmer step, or add fresh basil at the end for a bright herbal note.
- Smokier flavor: Use a smoked paprika pinch or swap in a more intensely smoked sausage.
Make-ahead and storage
Leftovers for this One Pot Penne Pasta Recipe keep well in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat with a splash of chicken stock or water to loosen the sauce and revive the creaminess. You can also microwave single portions, stirring halfway through and adding a little liquid if the pasta looks dry.
Serving suggestions
Serve this pasta with a crisp green salad and a simple vinaigrette to cut through the richness, or pair it with steamed green beans or roasted broccoli. Warm crusty bread or garlic bread is perfect for sopping up any leftover sauce.
