2. Ingredients for Chicken Alfredo Stuffed Spaghetti Squash

  • 2 spaghetti squash (small)
  • 1 1/2 Tbsp. butter
  • 1 clove garlic (minced)
  • 2 Tbsp. flour
  • 1 1/4 cup half-and-half
  • 1/2 tsp. salt
  • Black pepper (to taste)
  • 1/2 cup shredded Parmesan cheese (or 1/3 cup grated Parmesan cheese)
  • 2 cup chicken breast (cooked, 8 oz., chopped into 1/2-inch pieces)
  • 1/2 cup shredded Italian cheese (mozzarella, provolone, or a blend)
  • 1 Tbsp. fresh parsley (minced, optional)

3. Directions:

3.1 Preheat

Preheat the oven to 400°F.

3.2 Prep

Line a baking sheet with parchment paper. Cut the ends from each spaghetti squash. Slice each squash in half lengthwise, and spoon out seeds from each half. Arrange the halves, cut side down, on the prepared baking sheet.

3.3 Oven

Roast the squash on middle rack of oven until it is fork tender, 50-55 minutes. While squash bakes, prepare the chicken Alfredo filling.

3.4 Stove

Set a medium saucepan over medium-high heat and add the butter. Once melted, add the minced garlic and saute until fragrant, about 30 seconds. Sprinkle the flour into the pan and whisk to form a paste. Cook for 30 seconds to 1 minute, then slowly pour the half-and-half into the pan, whisking to dissolve flour.

Cook the sauce, whisking constantly, until it begins to bubble and thicken. Once thickened, turn off the heat. Add the salt, black pepper, and Parmesan. Stir until cheese is melted. Fold in the chopped cooked chicken.

3.5 Prep

Remove baking sheet from oven and flip squash halves so they are cut side up. Use a fork to toss the strands in each half. Divide the chicken Alfredo mixture evenly among squash halves, gently packing it into the cavity. Sprinkle the shredded cheese evenly over each mound of filling.

3.6 Oven

Return baking sheet to middle rack of oven. Bake until cheese is melted and lightly golden and filling is gently bubbling, 10-15 minutes.

3.7 Check

Check to see that squash is done. Remove from oven or add time as needed.

3.8 Serve

Transfer squash halves to serving plates and sprinkle with minced parsley, if desired. Serve immediately.
