Ingredients Overview for Creamy Roasted Red Pepper Chicken Penne Alfredo

Penne pasta — Use regular or whole wheat penne; substitute with rigatoni or fusilli if needed.

Roasted red peppers — Jarred work great, though roasting your own adds fresh smokiness; sub with roasted red pepper soup inspiration like https://myrecipecast.com/roasted-red-pepper-soup/ when you want even more depth. {Internal 2}
Heavy cream — For that classic silky texture; swap for half-and-half plus a tablespoon of butter if you want it lighter.
Parmesan cheese — Freshly grated keeps the sauce smooth; sub with Pecorino for a saltier bite.
Garlic — Minced; but if you love garlic, throw in an extra clove.
Butter and olive oil — For cooking and flavor.
Chicken broth — Helps thin the sauce and adds savory notes; sub with vegetable broth for a lighter base.
Smoked paprika — Tiny pinch for warmth; optional but nice.
Salt and pepper — To taste.
Fresh basil or parsley — For brightness on top.

How To Make Creamy Roasted Red Pepper Chicken Penne Alfredo

Step 1: Cook the pasta — Boil salted water and cook the penne until just shy of al dente, because the sauce will finish it off. {5} Reserve a cup of pasta water before draining.
Step 2: Sear the chicken — Season the chicken and sauté in a mix of butter and oil until golden and cooked through, then set aside. {6}
Step 3: Build the sauce — In the same pan, sauté garlic for 30 seconds, then add chopped roasted red peppers and a splash of chicken broth. {7} Let it simmer for a few minutes so the peppers break down.
Step 4: Blend until smooth — Transfer the pepper mix to a blender and pulse until creamy. {8} Return to the pan and stir in heavy cream and grated Parmesan, whisking until bubbly and silky.
Step 5: Combine — Toss the cooked penne and chicken into the sauce, stirring gently. {9} If it looks too thick, add reserved pasta water a little at a time until the texture is perfect.
Step 6: Finish with fresh herbs and serve — Scatter chopped basil or parsley and a final grating of cheese. {10} Taste and adjust salt and pepper. The sauce should cling to the pasta like a warm blanket.

Serving ideas and simple pairings

Serve Creamy Roasted Red Pepper Chicken Penne Alfredo with a crisp green salad and a wedge of lemon for brightness. {11} You can add a sprinkle of chili flakes if you like a little heat, and for a cozy twist serve it in shallow bowls with crusty bread. {12} Add roasted veggies on the side for more color and a veggie boost.

Tips For the perfect Creamy Roasted Red Pepper Chicken Penne Alfredo

Use jarred roasted red peppers when you are short on time, but roast your own when you want extra smoky depth. {13}
Don’t overcook the pasta; finish in the sauce so it soaks up flavor. {14}
Save pasta water; it helps loosen the sauce without watering it down. {15}
Grate your own Parmesan for better melting and less gritty texture. {16}
If you want a thicker sauce, simmer a minute longer; for thinner, add reserved pasta water slowly. {17}
For a lighter version, swap half the cream for low-fat milk and add a tablespoon of cornstarch mixed with cold water to thicken. {18}

Q&A
