CHEESY SPAGHETTI SQUASH CASSEROLE



Cheesy Spaghetti Squash Casserole image

I had a recipe for a 4-cheese baked spaghetti squash that I really liked, but it was hard to eat. It was baked in the shell of the squash, and then mixed together after baking. I wanted to try it as a casserole, and after a few tries, this is what I came up with.

Time 1h50m

Yield 10

Number Of Ingredients 20

1 (3 pound) spaghetti squash, halved and seeded
2 tablespoons olive oil, divided, or as needed
¼ teaspoon garlic-pepper seasoning, divided, or more to taste
1 (16 ounce) package sliced fresh mushrooms
1 large onion, diced
1 medium jalapeno pepper, seeded and diced
1 bulb garlic, cloves peeled and minced
1 pound ground pork sausage
1 ½ teaspoons fennel seeds
salt and ground black pepper to taste
1 pound broccoli, stem removed and broken into florets
2 tablespoons chicken soup base (such as Better than Bouillon®)
1 ½ teaspoons dried oregano
1 ½ teaspoons ground thyme
1 ½ teaspoons dried basil
1 ½ cups grated Parmesan cheese
1 ½ cups shredded Cheddar cheese
1 ½ cups shredded mozzarella cheese
nonstick cooking spray
1 ½ cups whipping cream

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.

Time 1h51m

Yield 6

Number Of Ingredients 11

1 spaghetti squash, halved and seeded
1 pound lean ground beef
½ cup finely chopped onion
½ cup minced bell pepper
1 clove garlic, minced
1 teaspoon dried basil
1 teaspoon dried oregano
½ teaspoon salt
¼ teaspoon ground black pepper
1 (14.5 ounce) can diced tomatoes, drained
⅓ cup shredded Cheddar cheese

Steps:

  • Preheat oven to 375 degrees F (190 degrees C). Place squash in baking pan; pour in enough boiling water to come 1/2-inch up the sides of dish.
  • Bake in the preheated oven until squash is tender, 40 to 45 minutes. Remove from oven; cool until easily handled, 7 to 10 minutes.
  • Reduce oven to 350 degrees F (175 degrees C). Scoop out squash; separate strands with a fork. Reserve shells.
  • Cook beef, onion, and bell pepper in a skillet over medium heat until the meat is no longer pink, about 5 minutes; drain.

Stir in squash; cook until liquid has evaporated, about 10 minutes.

Tips:

  • Choose the right spaghetti squash. Look for a squash that is firm and heavy for its size, with a deep yellow color. Avoid squash that has bruises or blemishes.
  • Cook the spaghetti squash properly. The best way to cook spaghetti squash is to bake it whole in the oven. Pierce the squash with a fork several times, then bake it at 400 degrees Fahrenheit for about 45 minutes, or until it is tender when pierced with a fork.
  • Use a sharp knife to shred the spaghetti squash. A sharp knife will make it easier to shred the squash into long, thin strands.
  • Don't overcook the sauce. The sauce should be simmered for just a few minutes, until it is heated through. Overcooking the sauce will make it watery and bland.
  • Season the casserole to taste. Add salt, pepper, and other seasonings to taste before baking the casserole.
  • Top the casserole with cheese before baking. This will give the casserole a golden brown crust.

Conclusion:

Spaghetti squash casserole is a delicious and easy-to-make dish that is perfect for a weeknight meal. It is a great way to use up leftover spaghetti squash, and it is also a healthy and affordable option. With a few simple tips, you can make a spaghetti squash casserole that is sure to please everyone at the table.
