- Large capacity deep-sided skillet
- Pot for boiling pasta

Ingredients
- 10 ounces penne pasta (provides a nice bite)
- 1-2 tablespoons olive oil (for cooking)
- 2-3 teaspoons Italian seasoning (adds flavor to chicken)
- Salt and pepper (for seasoning)
- 3 large boneless skinless chicken breasts, cut into bite-sized pieces (main protein)
- 3 tablespoons butter (for making the sauce)
- 1 tablespoon minced garlic (adds depth to flavor)
- ¼ cup all-purpose flour (for thickening the sauce)
- 1 ¼ cups chicken broth (base for the sauce)

How to Make Decadent Creamy Pesto Chicken Pasta Bake
Step 1. Start off by preparing the penne pasta according to the package instructions. You want it to be cooked al dente, meaning it should have a slight bite to it. Once it’s done, drain it and set it aside for later.
Step 2. While the pasta is cooking, season the bite-sized pieces of chicken breast with Italian seasoning, salt, and pepper according to your taste. This step adds essential flavor to the chicken, ensuring it shines in the final dish.
Step 3. Heat your large capacity skillet over medium heat and drizzle in the olive oil. Once the oil is shimmering, carefully add the seasoned chicken pieces. Cook them until there’s no pink left, allowing some browning to occur on all sides. Once the chicken is cooked through, transfer it to a plate.
Step 4. Bring the skillet back to the heat and melt the butter. Once melted, toss in the minced garlic and sauté it until it’s beautifully browned and fragrant. This will create a lovely base for your creamy sauce.
Step 5. At this point, sprinkle the flour over the garlic and butter mixture, stirring it in. Cook this for a couple of minutes until the flour turns golden and starts to smell nutty, which indicates it’s ready to be used as a thickening agent in your sauce.
Step 6. Slowly pour the chicken broth into the skillet while scrapping up any bits from the bottom of the pan. Whisk it in thoroughly, which helps develop the sauce’s flavor and texture.
Step 7. Next, add the half-and-half, stirring it in as the mixture begins to simmer gently over medium heat. Add the Romano cheese and basil pesto, stirring until the sauce slightly thickens and the cheese is melted, creating that creamy consistency you’re aiming for.
Step 8. Finally, add the cooked pasta and browned chicken back into the skillet. Stir everything together until the pasta and chicken are nicely coated in the creamy pesto sauce, ensuring each bite is packed with flavor.
Step 9. Once all the ingredients are combined, remove the skillet from the heat and plate up. Garnish with fresh torn basil leaves to add color and freshness to the dish before serving.
Serving Ideas for Decadent Creamy Pesto Chicken Pasta Bake
This creamy bake is great as a standalone meal, leaving little need for elaborate sides. A simple green salad with a light vinaigrette complements its richness nicely. For those looking to use leftovers, reheating is easy, and the flavors often deepen with time. Pairing it with garlic bread makes for a cozy meal, perfect for family gatherings or a low-key dinner with friends.
Practical Tips for Decadent Creamy Pesto Chicken Pasta Bake
- For an added depth of flavor, consider marinating the chicken in olive oil, Italian seasoning, and a little lemon juice for a while before cooking.
- When sautéing the garlic, watch it closely to prevent burning; it should be golden brown and fragrant, not dark and bitter.
- If the sauce thickens too much, a splash of additional chicken broth can help loosen it up.
- Be sure not to overcook the pasta; it should remain slightly firm since it will continue to cook when added to the hot sauce.
Common Mistakes to Avoid
1. Overcooking the Chicken Cooking the chicken too long can make it dry and tough. Monitor it closely, removing it from the skillet as soon as it’s no longer pink for juicy pieces.
2. Burning the Garlic If you let the minced garlic tan too dark, it can develop a bitter taste. Keep stirring and don’t walk away; it only takes a moment to burn.
3. Not Deglazing the Pan Skipping the deglazing step means losing out on the flavor that develops from the fond at the bottom. Be sure to scrape it up when adding the broth.
4. Using Cold Ingredients Having cold half-and-half or broth can shock the skillet’s temperature when added. Allow them to come close to room temperature for a smoother sauce.
5. Adding Too Much Flour If you add too much flour, the sauce can become gummy. Start with the specified amounts and adjust if needed while watching for the right thickness.
6. Not Adding Enough Salt Always taste your sauce before serving. If it’s lacking flavor, a pinch of salt can enhance all the other ingredients.
Simple Variations
To vary the recipe while keeping with your original theme, consider mixing up the pasta type or using a different protein such as shrimp or turkey. Keep in mind these will change the cooking time or process slightly, so stay alert and adjust as needed.
Storage & Reheating
For safe storage, let the pasta bake cool to room temperature before transferring it to an airtight container. In the fridge, it should stay fresh for up to three days. It can also be frozen for a longer shelf life, just be cautious with the cream as it may change texture slightly upon reheating. Reheat in the oven or on the stovetop, adding a little broth if it seems dry.
