1/4cupchopped fresh flat-leaf parsley, plus more for serving
1egg, beaten
3clovesgarlic, grated
1 25-oz.jar marinara sauce
1oz.sliced Provolone cheese, about 5-6 slices
Instructions
Preheat oven to 400 degrees. Rub cut sides of squash with 1 tablespoon of oil; season with 1/4 teaspoon salt and 1/2 teaspoon of pepper. Place, cut side down, on a baking sheet lined with parchment paper. Bake until tender when pierced with a fork, about 30 minutes. Let cool for 10 minutes. Scrape out flesh with a fork (discarding skin), creating spaghetti-like strands.
While squash bakes, mix chicken, bread crumbs, Parmesan, parsley, egg, garlic, 2 tablespoons oil and remaining 1/2 teaspoon each salt and pepper in a large bowl; shape into 16 balls.
Heat remaining 1 tablespoon oil in large ovenproof skillet over medium high. Working in two batches, cook meatballs, turning to brown, about 4 minutes for each set. Return all meatballs to the skillet.
Pour marinara over the meatballs and bring to a simmer over medium high. Top with Provolone slices and transfer to oven; bake until a thermometer inserted in the middle of a meatball registers 165 degrees and the cheese is melted and bubbly, about 10 minutes. Serve over spaghetti squash. Garnish with parsley and additional Parmesan cheese, if desired. Enjoy!
