Ingredients (Serves 4)
For the Spaghetti Squash
- 1 large spaghetti squash (about 1.2–1.5 kg / 2.5–3 lbs)
- 2 tablespoons olive oil
- Salt and black pepper
For the Chicken
- 2 large chicken breasts (about 450 g / 1 lb)
- 1 teaspoon Italian seasoning
- ½ teaspoon garlic powder
- Salt and pepper
- 1 tablespoon olive oil
For the Alfredo Sauce
- 2 tablespoons butter
- 3 cloves garlic, minced
- 1 cup heavy cream
- ¾ cup freshly grated Parmesan cheese
- ½ cup cream cheese (for extra richness and thickness)
- ¼ teaspoon nutmeg (optional but recommended)
- Salt and black pepper to taste
Optional Add-Ins
- Steamed broccoli
- Sautéed mushrooms
- Baby spinach
- Fresh parsley for garnish
Step 1: Roast the Spaghetti Squash
Preheat oven to 200°C (400°F).
Carefully cut the spaghetti squash lengthwise. Scoop out seeds with a spoon.
Drizzle the inside with olive oil and season with salt and pepper.
Place cut-side down on a baking sheet lined with parchment paper.
Roast for 35–45 minutes, depending on size, until fork-tender.
The squash is ready when a fork easily shreds the flesh into spaghetti-like strands.
Remove from oven and let cool slightly. Use a fork to scrape the strands into a bowl.
Set aside.
Step 2: Cook the Chicken
While the squash roasts, prepare the chicken.
Season chicken breasts with Italian seasoning, garlic powder, salt, and pepper.
Heat olive oil in a skillet over medium heat.
Cook chicken 5–7 minutes per side until golden and cooked through (internal temperature 75°C / 165°F).
Remove from pan and let rest for 5 minutes.
Slice into thin strips or bite-sized pieces.
Resting the chicken keeps it juicy.
Step 3: Make the Alfredo Sauce
In the same skillet (reduce heat to medium-low), melt butter.
Add minced garlic and sauté for 1 minute until fragrant. Do not brown.
Pour in heavy cream and bring to a gentle simmer.
Stir in cream cheese and whisk until smooth.
Add grated Parmesan gradually, stirring constantly until melted and thickened.
Season with salt, black pepper, and a pinch of nutmeg.
Let simmer 3–5 minutes until sauce coats the back of a spoon.
If too thick, add a splash of milk or chicken broth.
If too thin, simmer slightly longer.
Step 4: Combine Everything
Add shredded spaghetti squash directly into the Alfredo sauce.
Gently toss to coat evenly.
Add sliced chicken and stir to combine.
Let everything simmer together 2–3 minutes so flavors meld.
Taste and adjust seasoning if needed.
Step 5: Garnish & Serve
Transfer to serving bowls.
Top with:
- Extra grated Parmesan
- Fresh parsley
- Cracked black pepper
Serve immediately while creamy and warm.
Flavor & Texture Experience
This dish delivers:
Creamy richness from Alfredo sauce
Savory depth from Parmesan
Tender, juicy chicken
Light, slightly sweet squash strands
The spaghetti squash absorbs sauce beautifully while keeping the dish lighter than traditional pasta.
Pro Tips for Success
Choose a Heavy Squash
Heavier squash means more moisture and better texture.
Don’t Overcook the Squash
Overcooking makes it watery. Check at 35 minutes.
Salt After Cooking
Spaghetti squash releases moisture — taste before adding extra salt.
Freshly Grated Parmesan is Essential
Pre-shredded cheese doesn’t melt as smoothly.
Optional Variations
Broccoli Chicken Alfredo
Add steamed broccoli florets for extra color and nutrition.
Mushroom Alfredo
Sauté sliced mushrooms before adding cream for earthy flavor.
Spicy Version
Add red pepper flakes to the sauce.
Extra Cheesy Bake
Transfer mixture to baking dish, top with mozzarella, and broil 3–5 minutes.
Make It Meal Prep Friendly
- Stores in refrigerator up to 4 days.
- Reheat gently with a splash of milk.
- Not ideal for freezing due to cream sauce texture.
