• 1 cup sliced mushrooms
• 3 cups penne pasta, uncooked

Notes on Ingredients and Swaps

This One Pot Penne Pasta Recipe uses smoked sausage for a smoky, savory backbone. If you prefer a different protein, feel free to use chicken sausage or turkey sausage that matches your dietary needs. The mushroom and spinach add earthiness and a subtle freshness; you can boost the vegetable ratio by stirring in extra greens or bell peppers. Use a good-quality chicken stock to build a flavorful base, and let the roasted red peppers — juices and all — contribute a sweet, tangy note to the sauce. The combination of Monterey Jack and Parmesan gives a melty, slightly nutty finish; if you’d like a sharper edge, swap some Monterey Jack for cheddar in equal measure.

Equipment

• Large, heavy-bottomed pot or deep skillet with lid
• Wooden spoon or silicone spatula
• Sharp knife and cutting board
• Measuring cups

Step-by-Step Instructions

The instructions below follow the same order as the ingredient list and make the cooking process straightforward. Read through once before starting, then follow the numbered steps for best results.

1. Prepare ingredients: Dice 1/2 medium onion, mince 2 cloves garlic, slice 1 cup mushrooms, and cut 1 pound smoked sausage into bite-sized slices. Open the 10-ounce jar of roasted red peppers and keep the peppers and their juices together. Measure out 3 cups uncooked penne, 2 cups chicken stock, 2 cups Monterey Jack cheese, 1/2 cup Parmesan cheese, and 2 cups spinach.
2. Brown the sausage: Heat your large pot or deep skillet over medium heat. Add the smoked sausage slices and cook, stirring occasionally, until the edges are nicely browned and the sausage releases some of its fat, about 4–6 minutes. If your sausage is very lean, add a teaspoon of oil to prevent sticking.
3. Soften the aromatics and mushrooms: Add the diced onion to the pot with the browned sausage. Cook, stirring, until the onion becomes translucent and soft, about 3 minutes. Stir in the minced garlic and sliced mushrooms, and sauté until the mushrooms release their moisture and begin to brown, another 3–4 minutes. This builds a savory base for the sauce.
4. Add penne and liquids: Pour the 3 cups of uncooked penne into the pot with the sausage and vegetables, and spread it evenly. Pour in 2 cups chicken stock or broth and add the entire jar of roasted red peppers including the liquid. Stir gently to combine so the pasta is submerged as much as possible.
5. Simmer the pasta: Increase the heat to bring the liquid to a gentle boil, then reduce to a simmer. Cover the pot with a lid and cook for about 10–12 minutes, stirring every few minutes to prevent sticking and to ensure even cooking. Cook until the penne is al dente — tender but still with a slight bite. If the liquid evaporates too quickly and the pasta is still undercooked, add a splash more stock or water and continue cooking a minute or two.
6. Incorporate the cheeses: Once the pasta is al dente and most of the liquid has been absorbed, reduce heat to low. Sprinkle in 2 cups Monterey Jack cheese and 1/2 cup Parmesan cheese. Stir continuously until the cheeses melt into a smooth, creamy sauce that coats the penne evenly. If the sauce feels too thick, add a tablespoon or two of stock to reach your desired consistency.
7. Wilt the spinach and finish: Add 2 cups spinach to the pot and fold it into the pasta and sauce. Cook for 1–2 minutes more, just until the spinach wilts and blends into the creamy mixture. Taste and adjust seasoning with salt and black pepper as needed. If you’d like a little brightness, a squeeze of fresh lemon juice stirs in beautifully here.
8. Serve: Remove the pot from heat. Let the pasta sit for a minute to thicken slightly, then serve hot. Garnish with an extra sprinkle of Parmesan or a few torn roasted red pepper strips if you like.

Tips for Perfect Results

• Use a heavy-bottomed pot to prevent burning and to ensure even heat distribution.
• Stir occasionally while simmering so that pasta cooks evenly and doesn’t stick to the bottom.
• Keep the roasted red pepper juices — they add essential flavor and help form the sauce.
• For a thicker sauce, let the dish rest a minute uncovered before serving so liquids reduce slightly.
• For extra creaminess, stir in a splash of cream or a couple tablespoons of cream cheese at the end.

Make-Ahead and Storage

This One Pot Penne Pasta Recipe reheats beautifully. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat on the stovetop over low heat with a splash of stock or water to loosen the sauce. You can also reheat in the microwave, stirring halfway through to ensure even warming. Note that the pasta will absorb sauce as it sits, so keep a little extra liquid on hand when reheating.

Variations and Add-Ins

• Vegetable-forward: Double the mushrooms and spinach, and add diced zucchini or bell pepper for more veggies.
• Spicier version: Add red pepper flakes when you stir in the garlic, or toss in chopped jalapeño with the onion.
• Herby finish: Stir in fresh basil, parsley, or oregano at the end for a herb-forward lift.
• Protein swap: Substitute the smoked sausage with sliced chicken sausage, turkey sausage, or cubed cooked chicken.
• Cheese changeup: Swap part of the Monterey Jack for sharp cheddar, fontina, or a little cream cheese for extra silkiness.

Frequently Asked Questions

Can I use a different pasta shape?
Yes. While this recipe calls for penne, short pasta shapes like rigatoni, fusilli, or farfalle will work. Keep an eye on cooking time as different shapes and sizes cook at slightly different rates.

My pan looks dry before the pasta is cooked. What should I do?
If the liquid has nearly evaporated and the pasta is still undercooked, add 1/4 cup more chicken stock or water, stir, and continue to simmer until done. Check every minute to avoid overcooking.

Can I make this dairy-free?
Yes. Replace the Monterey Jack and Parmesan with dairy-free melty cheeses or a blend of nutritional yeast and a tablespoon of olive oil per serving to approximate a cheesy flavor. The texture will be slightly different but still delicious.

Serving Suggestions

This One Pot Penne Pasta Recipe is hearty enough to serve on its own, but here are a few simple sides that pair nicely:

• Arugula salad with lemon vinaigrette for a bright contrast.
• Toasted garlic bread or focaccia to mop up any remaining sauce.
• Roasted vegetables for an extra veggie boost — think broccoli, carrots, or Brussels sprouts.
