Best Cheesy Chicken Spaghetti Squash Casserole Recipes

SPAGHETTI SQUASH CASSEROLE WITH CHICKEN

Steps:

• Preheat the oven to 425 degrees F (220 degrees C).
• Drizzle cut sides of spaghetti squash with 1 tablespoon olive oil and season with salt and pepper. Place on a sheet pan with the cut sides down.
• Roast in the preheated oven until a fork easily penetrates the skin, about 30 minutes. Remove from the oven and set aside until cool enough to handle. Shred flesh with a fork until it resembles spaghetti noodles; transfer to a colander to drain for 20 minutes. Lower oven temperature to 350 degrees F (175 degrees C).
• While squash is draining, heat remaining olive oil in a skillet over medium heat. Add onion; cook and stir for 2 minutes. Stir in garlic and cook until fragrant, about 1 minute. Add ground chicken and season with salt and pepper. Cook until chicken is browned and crumbly with no pink remaining, 5 to 7 minutes. Remove from the heat and stir in spaghetti sauce.
• Transfer drained squash to a 9x13-inch casserole dish. Add sauce mixture, spinach, 1/2 of the mozzarella cheese and 1/2 of the Parmesan cheese; toss to combine. Sprinkle remaining cheeses over the top.
• Bake in the preheated oven until casserole is bubbling and cheeses have melted, about 20 minutes.

• With a fork, remove the "spaghetti" from the squash.

CHEESY SPAGHETTI SQUASH CASSEROLE

Steps:

• Preheat the oven to 350 degrees F (175 degrees C).
• Brush the squash flesh with 1 tablespoon olive oil and sprinkle 1/8 teaspoon garlic-pepper over top; rub the edges and insides to make sure it's distributed evenly. Place on a baking sheet.
• Bake in the preheated oven until tender when pierced with a fork, 45 to 60 minutes.
• Meanwhile, heat 1 tablespoon olive oil in a large cast iron pan over low heat. Add mushrooms, onion, and jalapeno and cook, stirring occasionally, for 30 minutes. Add garlic and cook for about 10 more minutes. Move everything to the outside edges of the pan; add sausage, fennel seeds, salt, and pepper to the center. Cook and stir until pork is browned, crumbly, and no longer pink, about 10 minutes. Fold in the broccoli and remove from the heat.
• Remove squash from the oven and set aside to cool a bit. Leave the oven on.
• Mix chicken base, oregano, thyme, and basil together in a large bowl. Add Parmesan cheese and mix thoroughly. Add Cheddar and mozzarella and mix until well combined; it may be a little clumpy, but as long as it's only small clumps, that's okay.
• Shred squash flesh onto a sheet pan; use an oven mitt to hold it if it's still too hot. Toss with remaining garlic-pepper and season with salt and pepper if you want to. (Just remember the chicken base has a fair amount of salt in it already.)
• Spray an 11x13-inch baking dish with nonstick spray. Spread 1/2 of the shredded squash evenly over the bottom of the dish and top with 1/2 of the pork-vegetable mixture. Repeat for a second layer. Pour cream over the entire dish.
• Bake, uncovered, in the preheated oven for 30 minutes.

CHEESY CHICKEN AND SQUASH CASSEROLE

Steps:

• Preheat the oven to 350 degrees F (175 degrees C). Grease a 2 1/2-quart baking dish and set aside.
• Bring about 5 cups of lightly salted water to a boil in a large saucepan or Dutch oven. Add squash, onion, parsley, thyme, and bay leaf. Bring back to a boil and cook over medium heat until squash is fork-tender, 3 to 5 minutes. Drain and discard parsley sprigs and bay leaf. Lightly press squash to remove additional liquid, then set aside.
• Wipe out the saucepan and return to the heat. Melt 4 tablespoons butter over medium heat. Sprinkle in flour and stir, working out any lumps, until flour and butter start to bubble, about 2 minutes. Gradually stir in milk and heat to a boil, stirring constantly. Cook and stir until sauce thickens, 4 to 5 minutes.
• Remove sauce from heat and stir in seasoned salt, Worcestershire sauce, and nutmeg. Drizzle 2 tablespoons into the egg yolks, stirring constantly to avoid lumps. Repeat with 2 additional tablespoons. Drizzle warmed eggs slowly back into the saucepan and stir until sauce is smooth. Stir in 1/2 of the Gruyere cheese and cayenne pepper. Season with salt and pepper.
• Place well drained squash and onion into the prepared baking dish. Top with chicken. Pour sauce over chicken and squash and stir gently to coat.
• Combine 2 teaspoons butter, remaining Gruyere cheese, and bread crumbs for the topping. Spread evenly over the casserole.
• Bake in the preheated oven until the top is browned and bubbly, about 35 minutes. Allow to cool for 10 minutes before serving. Garnish with chopped parsley.
