🔪 How to Make Skinny Chicken Alfredo Stuffed Spaghetti Squash
Follow these simple, step-by-step directions to make the perfect dish every time.
Step 1: Roast the Spaghetti Squash
- Preheat the oven to 400°F (200°C).
- Cut each spaghetti squash in half lengthwise and scoop out the seeds.
- Brush the inside lightly with olive oil and sprinkle with salt and pepper.
- Place the halves cut-side down on a lined baking tray.
- Roast for 30–40 minutes, or until the flesh becomes tender and easy to shred.
Pro tip: When done, the skin should yield slightly to pressure. Allow to cool before handling.
Step 2: Cook the Chicken
- In a large skillet, heat olive oil over medium heat.
- Season chicken breasts with salt, pepper, and a pinch of garlic powder.
- Cook for 7–8 minutes per side, until fully cooked through and golden.
- Remove from the pan, let it rest for 5 minutes, then shred using two forks.
If you’re in a hurry, you can use pre-cooked or leftover shredded chicken to save time.
Step 3: Make the Creamy Cauliflower Alfredo Sauce
Here’s the real magic of this dish — the cauliflower Alfredo sauce that feels rich but remains light and healthy.
- Steam or boil cauliflower florets until very soft (about 8–10 minutes).
- In a blender, add:
- Steamed cauliflower
- Chicken broth
- Parmesan cheese
- Garlic powder
- A dash of salt and pepper
- Blend until smooth and creamy. If it’s too thick, add a little more broth for a silky consistency.
Optional: Add 1 tablespoon of Greek yogurt for extra creaminess and protein.
Step 4: Combine Everything
- In a mixing bowl, combine shredded chicken with your creamy Alfredo sauce.
- Use a fork to scrape the roasted spaghetti squash into strands (they’ll look like noodles).
- Gently toss the squash strands with the chicken Alfredo mixture until fully coated.
- Taste and adjust seasoning — you can add more garlic, cheese, or herbs as needed.
Step 5: Stuff and Bake
- Spoon the creamy mixture back into the empty squash shells.
- Sprinkle a little extra parmesan or mozzarella cheese on top if desired.
- Return to the oven and bake for 10–15 minutes, or until the top is golden and bubbling.
Remove from oven and let rest for a few minutes before serving. The aroma will make it hard to wait!
🧀 Pro Tips for the Perfect Skinny Alfredo
- Use freshly grated parmesan: It melts better and gives a more authentic flavor than packaged cheese.
- Don’t overcook the squash: You want tender strands, not mushy ones.
- Balance the sauce: If the sauce feels bland, add a tiny pinch of salt and a squeeze of lemon juice — it brightens the flavors beautifully.
- Want it extra creamy? Add a tablespoon of light cream cheese to the sauce for extra body.
- For a crispier top: Broil the stuffed squash for the last 3–4 minutes until lightly browned.
