Ingredients You’ll Need (Serves 4)
For the spaghetti squash base:
- 2 medium spaghetti squash (about 2 ½ – 3 lbs each)
- 2 tablespoons olive oil
- ½ teaspoon salt
- ¼ teaspoon black pepper
For the green chile chicken filling:
- 2 cups cooked, shredded chicken breast (rotisserie chicken works great)
- 1 (4 oz) can diced green chiles, mild or hot
- ½ cup sour cream (or Greek yogurt for lighter option)
- ½ cup mayonnaise
- 1 cup shredded Monterey Jack cheese (plus ½ cup for topping)
- ½ cup shredded cheddar cheese
- 2 cloves garlic, minced
- ½ teaspoon cumin
- ½ teaspoon chili powder
- ¼ teaspoon paprika
- Salt and pepper, to taste
- 2 tablespoons chopped fresh cilantro (optional)
Step-by-Step Instructions
- Roast the Spaghetti Squash
- Preheat oven to 400°F (200°C).
- Carefully cut each spaghetti squash in half lengthwise and scoop out the seeds.
- Drizzle the cut sides with olive oil, then season with salt and pepper.
- Place cut-side down on a parchment-lined baking sheet.
- Roast for 35–40 minutes, or until the flesh is tender and easily shredded with a fork.
- Make the Green Chile Chicken Filling
- In a large mixing bowl, combine shredded chicken, diced green chiles, sour cream, mayonnaise, 1 cup Monterey Jack cheese, cheddar cheese, garlic, cumin, chili powder, paprika, salt, and pepper.
- Mix until everything is creamy and evenly combined.
- Shred the Squash
- Once the squash is cool enough to handle, use a fork to scrape the flesh into spaghetti-like strands.
- Leave the strands inside the squash shells (these will be your “boats”).
- Stuff the Squash
- Add the shredded squash strands into the chicken mixture and stir until combined.
- Spoon the mixture back into the squash shells.
- Top each with remaining Monterey Jack cheese.
- Bake & Serve
- Return stuffed squash halves to the oven.
- Bake for 10–15 minutes, or until cheese is melted and bubbly.
- Garnish with fresh cilantro if desired. Serve hot and enjoy!

Serving Suggestions
Serve with a crisp romaine or mixed greens salad to balance the richness. Pair with black beans, salsa, and guacamole for a Southwest-style feast. Enjoy with roasted veggies or steamed broccoli for extra nutrients.
Variations & Substitutions
Make it spicy by adding a minced jalapeño or a splash of hot sauce to the filling. Swap chicken for shredded turkey, ground beef, or even shrimp. Use Pepper Jack, Colby, or a Mexican blend for a different cheese profile. Make it dairy-free with vegan mayo, coconut yogurt, and dairy-free cheese shreds. Add sautéed onions, bell peppers, or spinach for extra veggies and color.
Pro Tips for Success
Cutting squash safely: If your squash is too tough to cut raw, poke it a few times with a fork and microwave for 3–4 minutes to soften. Don’t over-roast — overcooked spaghetti squash can get mushy. For golden bubbly cheese, switch the oven to broil for the last 1–2 minutes. Roast squash and prep filling up to 2 days ahead for easy assembly. Freeze the filling (without the squash shells) for up to 2 months — thaw before baking.
