Directions: One Pot Chicken Tetrazzini
Step 1: Sauté the Chicken
Begin by melting 2 tablespoons of the butter in a large pot or Dutch oven over medium heat. Once the butter is melted and bubbly, add the cubed chicken breast. Sprinkle with salt, pepper, and garlic powder (if using). Sauté the chicken for about 5-7 minutes, or until it’s browned and cooked through. Remove the chicken from the pot and set it aside.
Step 2: Cook the Mushrooms
In the same pot, add the remaining 2 tablespoons of butter. Once melted, add the sliced mushrooms. Sauté for 4-5 minutes until the mushrooms are tender and have released their moisture.
Step 3: Create the Sauce
Sprinkle the flour over the sautéed mushrooms, stirring to coat them evenly. Cook for another 1-2 minutes to eliminate the raw flour taste. Gradually pour in the chicken broth while stirring to prevent lumps. Then, add the milk, stirring until the mixture is smooth and begins to thicken.
Step 4: Add the Pasta
Bring the mixture to a gentle boil. Add the uncooked pasta to the pot, stirring well to combine. Reduce the heat to low, cover the pot, and let it simmer for about 10-12 minutes, stirring occasionally, until the pasta is cooked al dente and has absorbed most of the liquid.
Step 5: Combine and Serve
Once the pasta is cooked, return the sautéed chicken to the pot. Stir in the Parmesan cheese until melted and creamy. Adjust seasoning with additional salt and pepper to taste. Serve hot, garnished with fresh chopped parsley for a pop of color and flavor.
Dietary Customizations
- Gluten-Free: Substitute regular pasta with gluten-free pasta.
- Dairy-Free: Use plant-based butter and a dairy-free milk alternative, such as almond or oat milk.
- Vegetarian: Omit the chicken and add more mushrooms or other vegetables like spinach or bell peppers.
- Low-Carb: Replace pasta with zucchini noodles or cauliflower rice.
Problems & Prevention
- Sticky Pasta: Make sure to stir the pasta occasionally while it cooks to prevent sticking. If it becomes too thick, add a splash more broth or milk.
- Grainy Sauce: Ensure to whisk the broth and milk in slowly to prevent lumps when adding to the flour.
- Overcooked Chicken: Cook the chicken until just done; it will cook a bit more when combined with the pasta.
- Too Thick: If the sauce becomes too thick, add more broth or milk until the desired consistency is reached.
Cooling, Storing & Rewarming
To cool One Pot Chicken Tetrazzini, allow it to sit at room temperature for no more than 2 hours. Once cooled, transfer to an airtight container and refrigerate for up to 3 days. For freezing, let the dish cool completely, then transfer it to a freezer-safe container for up to 3 months. To rewarm, gently heat on the stovetop over low heat, adding a splash of broth or milk to loosen the sauce, or microwave in short bursts until heated through.
Troubleshooting Q&A
Can I use leftover chicken for this recipe?
Absolutely! If you have leftover rotisserie chicken or any other cooked chicken, simply add it towards the end of the cooking process to warm it through without overcooking.
What can I substitute for chicken broth?
You can use vegetable broth for a vegetarian option or even water in a pinch. However, vegetable broth will provide more flavor than water.
Why did my sauce turn out too thick?
If your sauce is too thick, it’s likely that the pasta absorbed too much liquid while cooking. You can easily fix it by adding a bit more broth or milk until it reaches your desired consistency.
Can I make this dish ahead of time?
Yes! You can prepare the dish up to the point of adding the pasta, then store it in the refrigerator for up to a day. When ready to serve, heat it up and continue with adding the pasta and cooking.
