Equipment

9x13 casserole dish

Ingredients

4 smaller chicken breasts or 2 large cut in half lengthwise
1 package Boursin cheese I used garlic & herb flavor (sub Kite Hill cream cheese for dairy free!
1 cup cherry tomatoes
2 tbsp olive oil
½ tsp salt + more to taste
½ tsp pepper
1 tsp garlic powder
1 tsp Italian seasoning
1 large spaghetti squash
½ cup pesto I like Delallo brand simply pesto!

Instructions

Preheat oven to 400. Add the Boursin to the center of a 9x13 inch casserole dish.
Place the chicken breasts and tomatoes around the cheese.
Drizzle with olive oil, then season the chicken breasts with the salt, pepper, garlic powder and Italian seasoning. Set aside.
Cut a spaghetti squash in half and scoop out the seeds (I like to cut in half around the smaller middle / not lengthwise - it’s so much easier!) Place cut-side down on a lined baking sheet.
Add the squash and the casserole dish into the oven at the same time and bake for 40 mins.
Shred the chicken (either on a cutting board or right in the dish) and add in the cooked squash noodles. Add in the pesto and toss everything together with the melted Boursin cheese.
Serve topped with Parmesan cheese and season with salt and pepper to taste. Enjoy!

Notes

- Nutrition facts: are for ⅙ of the total recipe
- Variations: Don’t have spaghetti squash on hand? Swap it for zucchini noodles, roasted sweet potatoes, or even gluten-free pasta. Want a protein boost? Add cooked shrimp or crumbled Italian sausage for a different spin. For a flavor twist, use sun-dried tomato pesto or add a handful of fresh spinach for extra greens.

- Even Chicken Cooking: If using large chicken breasts, slice them in half lengthwise for even roasting.

- Spaghetti Squash Shortcut: Microwave the squash for 4–5 minutes before cutting to soften the rind.

- Dairy-Free Option: Use Kite Hill cream cheese as a Boursin alternative, and a dairy-free pesto. There’s also a dairy-free Boursin cheese– if you can find it at your local grocery store, I recommend trying it!
- Storage: Store leftover Boursin chicken in an airtight container for up to 3 days. To reheat, warm in the oven at 350°F until heated through or microwave in 1-minute intervals.
