Ingredient Selection Tips
Choose a firm spaghetti squash with an intact outer skin and no soft spots. Fresh broccoli and bell pepper provide a pleasant contrast to the tender squash, while good-quality Italian chicken sausage contributes the main savory flavor.
For a recipe made with carefully selected ingredients, check the labels on your pesto and sun-dried tomatoes. Choose products packed in olive oil rather than canola oil if that is important to your dietary preferences.
Pesto has a concentrated flavor, so begin with a modest amount and adjust according to taste.
How to Make Italian Chicken Pesto with Spaghetti Squash
Step 1: Prepare and Roast the Squash
Preheat the oven to 350°F (175°C). Carefully cut the spaghetti squash in half lengthwise and remove the seeds. Sprinkle the cut surfaces with Italian seasoning.
Place the squash halves cut-side down on a rimmed baking sheet or roasting pan. Pour approximately 1 inch of water into the pan to help create steam during baking.
Roast for 35 to 40 minutes, or until the flesh is tender enough to separate easily with a fork. Cooking time may vary depending on the size of the squash.
Remove the pan from the oven and allow the squash to cool for about 10 minutes. Once it is cool enough to handle, scrape the flesh with a fork to create long, noodle-like strands. Set the strands aside.
Step 2: Brown the Chicken Sausage
Place a large skillet or wok over medium heat. Add the Italian chicken sausage after removing its casings.
Cook the sausage uncovered for approximately 10 minutes, breaking it into small crumbles with a spatula as it browns. Stir frequently to promote even cooking and prevent sticking.
Continue cooking until the sausage is browned and reaches a safe internal temperature of 165°F (74°C). If excess fat accumulates, carefully drain it before proceeding.
Step 3: Cook the Vegetables
Add the bite-size broccoli florets and green bell pepper pieces directly to the skillet with the browned sausage.
Stir to distribute the vegetables evenly throughout the meat. Cook until the broccoli begins to soften and the pepper becomes slightly tender while retaining some texture.
If the vegetables need additional moisture to cook, add a small splash of water and cover the skillet briefly.
Step 4: Add the Squash and Seasonings
Reduce the heat to low and add the roasted spaghetti squash strands to the skillet. Gently toss the mixture so the squash combines with the sausage and vegetables without becoming mashed.
Drizzle the olive oil over the ingredients. Add the chopped fresh basil, rosemary, and additional Italian seasoning to taste.
Stir carefully to distribute the herbs and oil throughout the skillet. Avoid using high heat at this stage, as it can cause the delicate herbs and oil to lose their fresh flavor.
Step 5: Stir in the Pesto and Tomatoes
Add two large spoonfuls of basil pesto to the skillet, followed by the sun-dried tomatoes. Gently fold everything together until the pesto coats the squash strands, sausage, and vegetables.
Taste the mixture and add more pesto if you prefer a stronger basil flavor. Allow the skillet to simmer gently over low heat for 2 to 5 minutes, just long enough for the ingredients to warm through and the flavors to combine.
Remove the skillet from the heat. Serve immediately with freshly grated Parmigiano-Reggiano if desired.
Helpful Cooking Tips
- Roast the squash until just tender: Overcooking can make the strands watery and mushy. Check the squash near the end of the baking time and remove it once the flesh separates easily.
- Allow the squash to cool before scraping: A short resting period makes it easier and safer to handle while helping the strands retain their shape.
- Break up the sausage evenly: Smaller crumbles distribute more consistently throughout the dish, so every serving contains a good balance of meat and vegetables.
- Keep the pesto on low heat: High temperatures can scorch the sauce and diminish its fresh herb flavor. Add it toward the end of cooking and stir gently.
- Adjust the sauce gradually: Start with a smaller quantity of pesto, taste the finished mixture, and add more if necessary. This allows you to control the intensity of the basil flavor.
- Use freshly grated cheese: Adding the optional cheese just before serving provides a savory finishing touch without requiring additional cooking.
Storage and Meal Prep
Refrigerating Leftovers
Allow the finished dish to cool slightly before transferring it into airtight food-storage containers. Refrigerate promptly and consume within three to four days.
For meal preparation, divide the cooled portions into individual containers. This makes it convenient to reheat a single serving without warming the entire batch.
Reheating Instructions
For the best texture, reheat the leftovers in a skillet over low heat. Stir gently for approximately three to five minutes, or until the mixture is heated through. If the squash appears dry, add a small splash of water to loosen the ingredients.
Microwave reheating is also possible. Place an individual portion in a microwave-safe container, cover loosely, and heat in short intervals, stirring between intervals until evenly warmed.
Preparing Ingredients Ahead
The spaghetti squash can be roasted and shredded ahead of time, then stored in the refrigerator until needed. Broccoli and bell pepper can also be washed and chopped in advance.
Keep the ingredients in separate airtight containers so they remain ready for quick assembly.
For the freshest flavor, add the pesto during the final cooking stage rather than mixing it into the ingredients too far ahead.
Serving Suggestions
Serve this chicken pesto skillet as a complete main course while it is warm. The combination of roasted squash, chicken sausage, and vegetables makes a substantial meal without the need for traditional pasta.
A little freshly grated Parmigiano-Reggiano and a sprinkle of chopped basil make a simple garnish. For a larger dinner spread, pair the skillet with a fresh green salad or roasted vegetables.
