High Protein Chicken Bacon Alfredo Spaghetti Squash - Creamy, Satisfying, and Weeknight-Friendly
Ingredients
Method
- Prep and roast the squash: Preheat oven to 400°F (200°C). Carefully halve the spaghetti squash lengthwise and scoop out the seeds. Rub the cut sides with a little olive oil, season with salt and pepper, and place cut-side down on a parchment-lined baking sheet. Roast 35–45 minutes, until the strands pull apart easily with a fork and are tender but not mushy.
- Crisp the bacon: While the squash roasts, cook bacon in a large skillet over medium heat until crisp. Transfer to a paper towel–lined plate. Crumble once cooled. Pour off most of the bacon fat, leaving about 1 teaspoon in the pan for flavor.
- Cook the chicken: Season chicken all over with salt, pepper, and half the Italian seasoning. Add 1 tablespoon olive oil to the same skillet over medium-high heat. Cook chicken 4–6 minutes per side, until browned and cooked through (165°F/74°C internal temp). Rest 5 minutes, then slice or cube.
- Start the sauce base: In the same skillet over medium heat, add butter (if using). Stir in minced garlic and cook 30–60 seconds until fragrant. Pour in chicken broth, scraping up browned bits. Reduce heat to medium-low and simmer 2 minutes.
- Make it creamy: Whisk in milk and remaining Italian seasoning. Sprinkle in Parmesan a little at a time, whisking until melted and smooth. Remove from heat and whisk in Greek yogurt until creamy. Season with salt, pepper, and crushed red pepper to taste.
- Shred the squash: When squash is cool enough to handle, use a fork to rake the flesh into spaghetti-like strands. Place strands in a large bowl and pat with paper towels if very wet.
- Toss it all together: Add squash strands, chicken, and most of the bacon to the skillet with the sauce. Toss gently over low heat until everything is coated and warmed through. If the sauce seems thick, add a splash of broth or milk. If too thin, stir in more Parmesan.
- Finish and serve: Taste and adjust seasoning. A small squeeze of lemon brightens the sauce nicely. Top with remaining bacon, extra Parmesan, and chopped parsley. Serve hot.
What Makes This Recipe So Good
- High in protein, lighter on carbs: Chicken and bacon add serious protein, while spaghetti squash keeps it balanced and satisfying.
- Creamy without being heavy: A mix of Parmesan, Greek yogurt, and a splash of milk creates a silky Alfredo-style sauce with fewer calories than the traditional version.

Easy, familiar techniques.

Storage Instructions
- Refrigerate: Store leftovers in an airtight container for 3–4 days.
- Reheat: Warm gently on the stovetop over low heat or in the microwave at 50–70% power.
Add a splash of milk or broth if the sauce tightens.
- Freeze: Not ideal. Greek yogurt and Parmesan can separate after thawing, and squash can get watery. If you must freeze, use airtight containers and thaw overnight in the fridge before reheating gently.
Benefits of This Recipe
- Protein-forward: Chicken and bacon deliver a solid protein hit to support satiety and muscle recovery.
- Lower in carbs: Spaghetti squash keeps calories and carbs in check without losing that cozy pasta vibe.
- Balanced richness: Greek yogurt and milk create a creamy sauce with less heavy cream, saving calories while keeping flavor.
- Micronutrient boost: Squash offers fiber, vitamin C, and beta carotene.
Fresh garlic and parsley add antioxidants and freshness.
- Customizable: Easy to scale, swap, or spice up to match your diet and taste.
What Not to Do
- Don’t over-roast the squash: Mushy strands turn watery and make the sauce thin. Pull it when just tender.
- Don’t add yogurt over high heat: Boiling can cause curdling. Take the pan off heat, then whisk it in.
- Don’t skip salting in layers: Season the chicken, the squash, and the sauce lightly for balanced flavor.
- Don’t dump all the Parmesan at once: Add gradually and whisk to prevent clumps and graininess.
- Don’t overcrowd the pan for chicken: You’ll steam instead of sear.
Work in batches if needed.
Alternatives
- Dairy-free: Use a creamy, unsweetened almond or cashew milk and a dairy-free Parmesan alternative. Swap Greek yogurt for a plain dairy-free yogurt or cashew cream. Add extra nutritional yeast for umami.
- Turkey bacon or pancetta: Both work well.
Turkey bacon is leaner; pancetta gives a deeper, savory note.
- Rotisserie chicken: A big time-saver. Shred and skip the stovetop chicken step.
- Veggie boost: Add sautéed spinach, peas, or roasted broccoli. Fold in at the end to keep textures bright.
- Spice it up: Stir in a pinch of cayenne or more crushed red pepper.
Blackened seasoning on the chicken is great too.
- Extra creamy: Swap half the milk for light cream, or add 1–2 ounces of low-fat cream cheese to the sauce.
- Herb swaps: Fresh basil or thyme instead of Italian seasoning for a different flavor profile.
FAQ
How do I cut spaghetti squash safely?
Place the squash on a towel to prevent slipping. Use a sharp chef’s knife to score a line lengthwise, then press down firmly to split. You can also microwave the whole squash for 3–4 minutes to soften the skin before cutting.
Can I make the sauce ahead of time?
Yes, but reheat gently over low heat and whisk in a splash of milk or broth to loosen.
Add the Greek yogurt after reheating to avoid separation.
What if my sauce curdles?
Remove from heat and whisk vigorously. Add a small splash of warm milk and more grated Parmesan to bring it back together. Next time, lower the heat before adding yogurt.
How do I keep the squash from being watery?
Roast cut-side down until just tender, then let it rest cut-side up for a few minutes.
After shredding, pat the strands with paper towels to absorb excess moisture.
Is there a way to make it even higher in protein?
Increase the chicken to 1.5 pounds, add turkey bacon, or stir in a scoop of unflavored whey isolate to the sauce off heat. Taste and adjust seasoning since whey can slightly change flavor and thickness.
Can I use jarred Alfredo sauce?
You can, but this homemade version is lighter and fresher. If using jarred sauce, thin with a bit of broth and brighten with lemon and extra Parmesan.
What side dishes go well with this?
A crisp green salad, roasted asparagus, or garlicky green beans pair nicely without competing with the creamy sauce.
Can I make it in the squash shells for serving?
Yes.
Toss squash strands with the sauce, chicken, and bacon, then spoon back into the shells. Sprinkle with Parmesan and broil 1–2 minutes until lightly golden.

High Protein Chicken Bacon Alfredo Spaghetti Squash hits that sweet spot between cozy and clean. It’s creamy, flavorful, and filling, yet lighter than classic pasta Alfredo.
