How to Make Pesto Chicken Stuffed Spaghetti Squash
Step 1: Roast the Spaghetti Squash
Start by cutting the spaghetti squash in half lengthwise and scooping out the seeds. Drizzle with olive oil and season with salt and pepper. Place cut side down on a baking sheet and roast in a preheated 400°F oven for about 40 minutes, or until the strands easily separate with a fork.
Step 2: Cook the Chicken
While the squash roasts, season chicken breasts with salt, pepper, and a little garlic powder. Heat olive oil in a skillet over medium heat and cook the chicken until golden and cooked through, about 5-7 minutes per side. Let it rest before slicing or shredding.
Step 3: Prepare the Pesto
Use store-bought pesto or blend fresh basil, pine nuts, garlic, Parmesan, and olive oil in a food processor until smooth. Adjust seasoning as needed.
Step 4: Combine and Stuff
Once the squash is cool enough to handle, use a fork to scrape the flesh into noodle-like strands. Mix the squash with the cooked chicken and pesto until evenly coated.
Step 5: Bake Together
Fill the roasted spaghetti squash shells with the pesto chicken mixture. Sprinkle with extra Parmesan cheese and bake at 375°F for 15 minutes, until warmed through and the cheese is melted and golden on top.
Pro Tips for Making Pesto Chicken Stuffed Spaghetti Squash
- Roast evenly: Cut squash halves evenly and keep the skin side down while roasting for consistent cooking.
- Chicken moisture: Avoid drying out chicken by resting it before slicing and using olive oil liberally.
- Pesto freshness: Use fresh pesto whenever possible—it dramatically brightens the flavor.
- Don’t overstuff: Leave some space in the squash shells to avoid spilling during baking.
- Cheese topping: Broil for 1-2 minutes at the end to crisp the cheese perfectly.
