2. Mixed Green Salad: A simple salad with mixed greens, cherry tomatoes, and a light vinaigrette offers a refreshing contrast to the rich pasta.
3. Grilled Chicken or Shrimp: For those looking to add protein, grilled chicken or shrimp pairs nicely. It rounds out the meal while adding some smokiness.
4. Roasted Vegetables: Seasonal roasted veggies, such as zucchini, bell peppers, or asparagus, can enhance the health quotient while adding depth to the meal.
5. Chardonnay or Pinot Grigio: When wine is on the menu, these whites can elegantly cut through the creaminess of the Alfredo sauce.

What is Spaghetti Squash and Broccoli Alfredo?
Spaghetti squash is a unique vegetable. Once cooked, its flesh separates into strands that resemble spaghetti. It’s packed with nutrients, low in calories, and gluten-free, making it a hit especially among health-conscious eaters. Paired with broccoli and a creamy Alfredo sauce, this dish takes the best of both worlds—vegetables and crème—and marries them beautifully.
The Alfredo itself is made with a base of Parmesan cheese, milk, and a touch of garlic. This creamy sauce envelops the spaghetti squash and broccoli, creating a dish that is comforting yet surprisingly light.
How Does It Taste?
The texture of spaghetti squash is a delightful contrast to the creamy sauce. It’s tender yet has a slight crunch. The broccoli adds a refreshing green note, while the garlic serves as a necessary kick that brightens everything up.
Each spoonful hits your palate with a subtle richness from the cheese without being overly heavy. You get a combination of flavors that keeps your taste buds dancing.

Ingredients
Here’s what you’ll need:
- ¾ cup grated Parmesan cheese
- 12 ounces boneless, skinless chicken breast, cut into bite-size pieces
- 1 (2½ to 3-pound) spaghetti squash, halved lengthwise and seeded
- ½ teaspoon salt
- 2 tablespoons avocado oil or extra-virgin olive oil
- ¼ teaspoon ground pepper
- 3 cups small broccoli florets
- 4 ounces fresh mozzarella cheese, patted dry and shredded (3/4 cup)
- 1 cup reduced-fat milk
- 2 tablespoons cornstarch
- 2 large cloves garlic, minced
- ¼ teaspoon red pepper flakes (for a subtle kick of heat)
- 1 tablespoon chopped fresh basil or parsley (for brightness)

Step-by-Step Directions
Let’s get cooking! Here’s how to bring it all together.
Step 1: Prepare the Spaghetti Squash
Begin by preheating your oven to 400°F (200°C). Next, slice the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle with olive oil and sprinkle with salt and pepper. Place the halves, cut-side down, on a baking sheet lined with parchment paper. Roast in the oven for about 30 to 40 minutes, or until you can easily pierce the skin with a fork.
Step 2: Cook the Chicken
While the squash is roasting, heat the avocado oil in a large skillet over medium heat. Add the chicken pieces, sprinkling them with salt and pepper. Sauté until the chicken is cooked through and lightly browned, about 6-8 minutes. Remove the chicken from the pan and set it aside.
Step 3: Sauté the Broccoli
In the same skillet, add the broccoli florets. Sauté for about 4-5 minutes, until they become tender yet still vibrant and crisp. You might want to add a splash of water to create steam if the pan is getting too dry.
Step 4: Make the Alfredo Sauce
Now, let’s make that luscious Alfredo sauce. Add the minced garlic to the broccoli and cook until fragrant, around 1 minute. In a medium bowl, whisk together the reduced-fat milk and cornstarch until smooth. Pour this mixture into the skillet. Stir consistently until the sauce thickens, about 3-4 minutes. Once thickened, stir in the Parmesan cheese and mozzarella until melted and creamy. Add red pepper flakes for a bit of heat.
Step 5: Combine Everything
Once the spaghetti squash is done, use a fork to scrape the flesh into strands. Combine the strands with the chicken, broccoli, and Alfredo sauce in the skillet. Toss everything gently until well-coated.
Step 6: Serve
Dish out your delicious spaghetti squash and broccoli Alfredo onto plates. Top with fresh basil or parsley. Enjoy immediately!
