INGREDIENTS
- 1 medium spaghetti squash
Choose one that feels firm and heavy. - 2 cups cooked chicken (shredded or cubed)
Rotisserie chicken works great. - 2 tablespoons butter
Adds rich flavor. - 3 cloves garlic (minced)
Fresh garlic gives the best taste. - 1 cup heavy cream
Creates a thick, creamy sauce. - 3/4 cup shredded parmesan cheese
Adds depth and thickness. - 1/2 teaspoon salt
Adjust to taste. - 1/4 teaspoon black pepper
Add mild spice.
Optional:
- Fresh parsley for garnish
- Red chili flakes for heat
HOW TO MAKE (STEP-BY-STEP)
1. Roast the spaghetti squash
Start by cutting the spaghetti squash in half lengthwise. Scoop out the seeds carefully. Drizzle a little oil on the inside and sprinkle salt and pepper. Place it cut-side down on a baking tray. Roast at 200°C (400°F) for about 35–40 minutes. The squash should feel soft when pressed. Let it cool slightly, then scrape with a fork to create strands. They should look soft, light, and slightly golden.
2. Prepare the chicken
While the squash is roasting, heat a pan over medium heat. Add butter and let it melt slowly. Add the cooked chicken and stir gently. Let it warm through without drying out. The chicken should stay juicy and tender. If using raw chicken, cook until golden and fully done before moving on.
3. Build the garlic flavor
Add minced garlic to the pan with chicken. Cook for 1–2 minutes until fragrant. The garlic should smell rich and slightly nutty. Be careful not to burn it. This step builds the base flavor of your Alfredo sauce.
4. Make the Alfredo sauce
Pour in heavy cream and stir slowly. Let it heat gently until slightly thick. Add parmesan cheese and mix until melted. The sauce should look smooth, creamy, and rich. Taste and adjust salt and pepper. Keep heat low to avoid splitting.
5. Combine everything
Add the spaghetti squash strands into the pan. Mix gently so the sauce coats every strand. The texture should look creamy and well combined. Do not overmix. Keep the strands light and soft.
6. Finish and serve
Cook for another 2–3 minutes so flavors blend together. Remove from heat and let it rest briefly. The dish should look glossy, creamy, and rich. Serve warm with parsley or chili flakes.
This small trick makes a huge difference…
Roasting the squash cut-side down keeps it tender instead of watery.
