How to Make Pesto Chicken Stuffed Spaghetti Squash
Step 1: Preheat the Oven
Preheat your oven to 375 degrees F. This ensures that your spaghetti squash cooks evenly when placed inside.
Step 2: Prepare the Spaghetti Squash
- Cut each spaghetti squash in half lengthwise.
- Dig out the seeds using a spoon.
- If needed, microwave each half for 5-10 minutes to make cutting easier.
Step 3: Bake the Squash
Place each squash half face down in a baking dish. Bake them in the preheated oven for 35-45 minutes, depending on their size. Once cooked, you should be able to fluff the strands with a fork easily.
Step 4: Cook the Chicken
Prepare your shredded chicken using your preferred method. Boiling chicken breasts takes about 20 minutes but consider using an instant pot or slow cooker for convenience.
Step 5: Make the Pesto
Combine all ingredients for homemade pesto in a food processor. Blend until mostly smooth. Alternatively, if time is short, feel free to use store-bought pesto.
Step 6: Mix Chicken and Pesto
In a large bowl, toss shredded chicken with prepared pesto. Gently fold in halved cherry tomatoes to add freshness to your filling.
Step 7: Fluff Up Squash
Once baked, use a fork to fluff up each spaghetti squash half. Scrape strands off the sides gently and season with salt and pepper.
Step 8: Fill Each Half
Distribute the chicken pesto mixture evenly across each half of the spaghetti squash. Make sure to fold it into the strands well. If desired, top with shredded cheese for additional flavor.
Step 9: Bake Again
Return stuffed spaghetti squash halves to the oven. Bake for an additional 20 minutes or until heated through completely.
