INGREDIENTS
- 1 medium spaghetti squash
Choose firm and heavy for the best texture. - 2 cups cooked chicken (shredded or cubed)
Rotisserie chicken saves time. - 2 tablespoons olive oil
Adds flavor and helps cooking. - 3 tablespoons pesto sauce
Use fresh or store-bought keto-friendly pesto. - 1/2 cup heavy cream
Optional for a creamy version. - 1/2 cup parmesan cheese
Adds depth and richness. - Salt and pepper to taste
Adjust slowly.
Optional:
- Cherry tomatoes for freshness
- Fresh basil for garnish
HOW TO MAKE (STEP-BY-STEP)
1. Roast the spaghetti squash
Start by cutting the spaghetti squash in half lengthwise. Scoop out the seeds. Drizzle olive oil and sprinkle salt and pepper. Place cut-side down on a baking tray. Roast at 200°C (400°F) for 35–40 minutes. The squash should feel soft when pressed. Let it cool slightly, then scrape with a fork. The strands should look soft, light, and slightly golden.
2. Prepare the chicken
Heat a pan over medium heat and add olive oil. Add the cooked chicken and warm it gently. The chicken should stay juicy, not dry. Stir slowly to heat evenly. If using raw chicken, cook fully until golden before continuing.
3. Add pesto flavor
Add pesto sauce into the pan with chicken. Stir gently so the chicken gets fully coated. The smell should be fresh, herby, and rich. Keep the heat low so the pesto doesn’t burn.
4. Make it creamy (optional)
If you want a creamy version, pour in heavy cream. Stir slowly until it blends with the pesto. The sauce should look smooth, slightly thick, and glossy. Add parmesan cheese and mix until melted.
5. Combine everything
Add the spaghetti squash strands into the pan. Mix gently so the sauce coats every strand. The texture should look soft and creamy but still light. Do not overmix to keep the strands intact.
6. Finish and serve
Cook for another 2–3 minutes so flavors combine. Remove from heat and let it rest briefly. The dish should look fresh, creamy, and slightly glossy. Garnish with basil or tomatoes if desired.
This small trick makes a huge difference…
Letting the squash cool slightly before mixing keeps it from getting watery.
