Essential Ingredients
- 1 tablespoon olive oil

- 1 lb boneless, skinless chicken breasts, cubed
- 12 oz dried penne pasta

Preparation Steps
- Sauté Aromatics:
In a large Dutch oven, heat olive oil over medium-high heat. Add chopped jalapeños and garlic, cooking for 30 seconds to 1 minute until fragrant. - Cook Chicken and Pasta:
Stir in the chicken pieces, pasta, and chicken stock. Bring to a boil, then cook uncovered for 4 minutes, stirring occasionally. Cover, reduce heat to medium-low, and simmer for 10–12 minutes until pasta is al dente and most of the liquid is absorbed. - Create the Sauce:
Uncover and add the chopped red bell pepper, cream, and salt. Stir to combine. Remove from heat. - Melt in the Cheese:
Gradually stir in Parmesan cheese in 2–3 additions until smooth. Add ¼ cup cheddar and stir again until creamy. Adjust salt to taste. - Serve:
Spoon into bowls. Top with remaining cheddar, jalapeño slices, and a drizzle of hot sauce if desired. Serve immediately.

Health Benefits
- Protein-packed: Chicken adds lean protein to keep you full and energized.
- Calcium-rich: Parmesan and cheddar contribute to your daily calcium intake.
- Capsaicin from jalapeños: Offers a metabolism boost and potential anti-inflammatory benefits.
- Balanced indulgence: The cream and cheese make it rich, but it’s balanced with lean meat and veggies.
Serving Suggestions
- Pair with a simple green salad to cut through the richness.
- Add garlic bread or toasted ciabatta on the side.
- Serve with a cold lager or sparkling water to mellow out the heat.
- Sprinkle with fresh parsley or green onions for a pop of color and freshness.
Creative Variations
- Vegetarian Swap: Replace chicken with sautéed mushrooms or plant-based chicken strips.
- Extra Veggies: Add spinach, zucchini, or corn for extra nutrition and texture.
- Spice It Up: Use fresh jalapeños or add cayenne for more heat.
- Different Cheese Combo: Swap cheddar with pepper jack or gouda for a new flavor twist.
- Pasta Alternatives: Use rotini or cavatappi instead of penne.
Storage Tips
- Refrigerate: Store leftovers in an airtight container for up to 3 days.
- Reheat: Gently warm on the stovetop with a splash of cream or milk to loosen the sauce.
- Freezing not recommended: Due to the cream-based sauce, freezing may affect texture.
Pro Tips
- Grate your own cheese for a smoother, meltier sauce—pre-shredded can be clumpy.
- Stir constantly while adding cheese to avoid clumps or separation.
- Use pickled jalapeños for a consistent, tangy heat that’s not overwhelming.
- Cook pasta just al dente—it will continue softening in the sauce.
