Step-by-Step: Pesto Spaghetti Squash with Chicken
1. Cook Spaghetti Squash
Option A—Roasting (40–50 minutes)
- Preheat Oven: 400°F (200°C).
- Halve & Seed: Slice squash lengthwise, scoop out seeds.
- Oil & Season: Brush inside with ~1 tablespoon olive oil, sprinkle salt/pepper.
- Roast: Place cut side down on a baking sheet ~30–40 minutes until a fork easily pierces rind. Time depends on squash size.
Option B—Microwave (10–12 minutes)
- Halve & Seed similarly, then place cut side down in a microwave-safe dish with ~1/2 cup water.
- Cook: 10–12 minutes, checking for fork-tender.
- Drain: Carefully remove, let cool.
Option C—Instant Pot (6–8 minutes)
- Halve: Remove seeds.
- Trivet: Place in pot with 1 cup water.
- Manual: ~7 minutes, then quick release.
2. Shred Squash Strands (2–3 minutes)
- Cool Briefly: Enough to handle without burning fingers.
- Fork: Gently rake inside flesh to create spaghetti-like strands. Transfer to a bowl.
3. Prepare or Warm Chicken (5–10 minutes)
If Using Raw Chicken
- Dice or Slice: 1 lb chicken breasts.
- Season: Salt, pepper, possibly a pinch of Italian seasoning or simple salt/pepper.
- Sauté: In a skillet over medium-high with ~1 tbsp olive oil, cooking ~5–6 minutes until ~165°F internally.
If Using Cooked Leftover Chicken
- Reheat: Shred or cube the chicken, warming in a skillet or microwave if you prefer a hot dish.
4. Combine with Pesto (2–3 minutes)
- Skillet or Bowl: For a warm dish, use a skillet on low heat or a large bowl if you prefer more minimal heating.
- Add Strands: Spaghetti squash + chicken.
- Pesto: ~1/2 cup or to taste. Stir gently, ensuring everything is coated.
- Season: Salt, pepper if needed. Optionally add a bit of lemon juice.
5. Final Touches & Serve (Immediate)
- Optional Cheese: Grate Parmesan over top.
- Extra Veggies: Mix in halved cherry tomatoes or fresh spinach leaves for color.
- Plate: Twirl squash on a plate, topping with any final garnishes.
Mastering the Texture & Flavor
- Avoid Overcooking Squash
Overly soft strands can turn mushy. Aim for a slight bite. - Quality Pesto
Homemade or a top-tier store-bought brand ensures vibrant basil flavor. - Light Sauté
If combining in a skillet, keep heat modest—just enough to meld flavors, not cook further.
Serving & Presentation

- Plates/Bowls: Mound in the center, drizzle extra pesto or olive oil if you want.
- Garnish: Fresh basil leaves, Parmesan shavings, or chopped pine nuts.
- Sides: A green salad, garlic bread, or a side of roasted vegetables can round out the meal.
Possible Variations
- Creamy Twist
Stir in a splash of heavy cream or cream cheese for a richer sauce. - Different Proteins
Sub grilled shrimp or turkey sausage for chicken. - Spicy Kick
Add red chili flakes or a pinch of cayenne to the pesto or final mixture. - No Pesto?
Use a tomato-based sauce or Alfredo. The process remains the same.
Dietary & Health Notes
- Low-Carb
Swapping out traditional pasta for spaghetti squash can drastically reduce carbs. - Protein & Veggie
Chicken plus squash and pesto yield a balanced meal with fiber, protein, and healthy fats (from olive oil/nuts). - Keto-Friendly
Check the net carbs in squash and omit sweeteners if any. Pesto typically aligns well with keto, provided no extra sugar.
Storing & Reheating
- Refrigerate: Combine leftover squash-chicken-pesto in a sealed container for up to ~3 days.
- Reheat: Gentle microwave or stovetop. The squash can soften further if overheated.
- No Freezing: Squash strands can become watery upon thawing, though still edible if you accept a change in texture.
Frequently Asked Questions
Q1: My spaghetti squash is watery.
Possibly overbaked. Drain or pat strands with paper towels. Next time, reduce cooking time or temperature.
Q2: Could I skip the chicken?
Sure—just do a vegetarian version. You could add mushrooms or extra veggies for substance.
Q3: Is jarred pesto high in sodium?
Often, yes. Compare labels or make your own. Homemade lets you control salt and quality.
Q4: Do I need to salt the squash before roasting?
Some people lightly salt to draw moisture, but it’s optional. Drizzling oil and minimal seasoning suffice.
Q5: Can I cook spaghetti squash whole?
Yes—poke holes, roast or microwave, but halving typically speeds cooking and makes seeds easier to remove.
