Save This wholesome Alfredo Stuffed Spaghetti Squash recipe transforms classic comfort food into a nourishing main dish. Roasted spaghetti squash halves are filled with juicy chicken, vibrant spinach, and a creamy garlic-Parmesan Alfredo sauce, then topped with melty mozzarella for a golden finish.
I first whipped this up on a chilly night when I craved something indulgent but still wanted plenty of veggies and protein. Now whenever I make it everyone in the house hurries to the table. The leftover halves also reheat perfectly for lunch the next day.
Ingredients
- Spaghetti squash: Provides the veggie noodle base Look for squash that feels heavy with a firm unblemished skin
- Olive oil: Helps the squash caramelize during roasting Use extra virgin for best flavor
- Salt and black pepper: Essential for seasoning Taste before roasting and adjust as needed
- Cooked chicken breast: Adds lean protein Rotisserie chicken or poached chicken works well
- Fresh baby spinach: Packs in vitamins and color Crisp leaves with no wilt spots guarantee quality
- Cremini or white mushrooms: Optional for extra umami Wipe clean and slice just before using
- Unsalted butter: Starts the Alfredo sauce Quality butter gives a silkier finish
- Garlic: Brings deep flavor Fresh cloves rather than pre minced delivers the best punch
- Heavy cream: Provides richness Avoid ultra pasteurized for smooth blending
- Whole milk: Balances the creaminess Use whole for texture or sub half and half for a lighter result
- Freshly grated Parmesan cheese: Delivers salty sharpness Grate it fresh for superior flavor and melting
- Ground nutmeg: Classic in Alfredo A dash warms up the sauce
- Shredded mozzarella cheese: Encourages a bubbly topping Part skim melts well but whole milk is more decadent
- Fresh parsley: Brightens the finish Use flat leaf if you can
Instructions
- Prep the Squash:
- Halve spaghetti squash lengthwise and scoop out seeds Drizzle each half with olive oil and season with salt and pepper Rub gently into the flesh so squash roasts evenly Place cut side down on a parchment lined baking sheet Roast at four hundred degrees for thirty five to forty minutes until strands pull apart easily with a fork
- Make the Alfredo Sauce:
- Melt unsalted butter in a medium saucepan over medium heat Add minced garlic and stir for one minute until just fragrant Pour in heavy cream and whole milk stirring constantly to prevent scorching Once mixture starts to bubble whisk in freshly grated Parmesan cheese and ground nutmeg Season with salt and pepper and continue whisking until the sauce thickens and turns glossy Remove from heat to prevent overcooking
- Prepare Chicken and Veggies:
- In a large mixing bowl add cooked chicken breast chopped spinach and mushrooms if using Pour in half of the warm Alfredo sauce Fold together gently so chicken stays tender and spinach wilts slightly
- Shred the Squash:
- Once squash halves are cool enough to handle use a fork to scrape flesh into spaghetti like strands Keep shells intact for stuffing Transfer strands to your mixing bowl and give everything a light toss to combine
- Stuff and Top:
- Spoon the chicken veggie squash mixture evenly back into the squash shells Pour remaining Alfredo sauce over each half and sprinkle generously with shredded mozzarella cheese so every bite will have melted topping
- Bake to Finish:
- Place stuffed halves back on your baking sheet Return them to the oven for ten to twelve minutes Bake just until cheese is melted and bubbling at the edges Remove and let cool slightly before garnishing with chopped fresh parsley
