Ingredients:
1 medium winter squash (about the size of a grapefruit or slightly larger), such as acorn, kabocha, red kuri, sweet dumpling, delicata, or spaghetti
2 to 3 cups filling (see below)Olive oilKosher salt
Freshly ground black pepper

General amounts for filling — to equal 2 to 3 cups total:

• 1/2 to 1 cup protein — ground sausage, ground beef, chicken, tempeh, or baked tofu
• 1 to 2 cups vegetables — onions, mushrooms, zucchini, peppers, greens
• 1/2 cup cooked grains and/or nuts — barley, quinoa, millet, farro, rice, walnuts, almonds, pecans
• 1/2 to 1 cup shredded cheese
• 1 to 3 teaspoons herbs or spices

Directions:
Arrange a rack in the lower-middle position of the oven and heat to 375°F. Cut the squash in half from stem to root. Scoop out the seeds.

Place the squash halves cut-side-down in a baking dish and pour in enough hot water to fill the pan by about 1/4 inch. Cover the dish loosely with aluminum foil.

Roast the squash until very soft and tender when poked with a fork or paring knife, 30 to 50 minutes. Exact roasting time will depend on the size and variety of your squash. While the squash is roasting, prepare the filling.

Depending on the size of your squash, 2 to 3 cups of combined ingredients is usually sufficient. You can combine leftovers from other meals (cooked chicken, roasted vegetables, etc.) or you can prepare a fresh filling. Cook any raw meats and raw vegetables and combine all the ingredients in a bowl. Taste and adjust the spices, salt, and pepper to your liking.

Flip the cooked squash halves so they form bowls. Rub the inside with a little olive oil and sprinkle with salt and pepper. Divide the filling between the halves — it's fine to really stuff the wells and also to mound the filling on top.

Cover again with the foil. Roast until heated through and bubbly, 15 to 20 minutes. Top with extra cheese if desired and serve immediately.

Ingredients:
1 small/medium spaghetti squash about 2 pounds
2 teaspoons extra-virgin olive oil
1 pound 93% lean ground turkey
1 small red onion diced
1 green bell pepper cored and diced
1 teaspoon kosher salt
½ teaspoon ground black pepper
1 can 14.5-ounce diced tomatoes with Italian spices, drained
3 cloves garlic minced
1 teaspoon Italian seasonings of choice or a mix of oregano, basil, and thyme
½ teaspoon crushed red pepper flakes reduce to 1/4 teaspoon if sensitive to spice
1 cup freshly grated part-skim mozzarella or provolone cheese divided
Chopped fresh parsley or basil

Directions:
Place a rack in the center of your oven and preheat the oven to 400 degrees F. Roast the spaghetti squash. When cool enough to handle, pull the squash strings out of the squash's center with a fork and transfer to a large mixing bowl. The squash strings should look like spaghetti.

Reduce the oven temperature to 350 degrees F. Heat the olive oil in a large, deep skillet over medium high. Add the turkey, onion, bell pepper, salt, and black pepper. Cook, breaking apart the meat, until meat is browned and the vegetables are tender, about 8 minutes. Add the drained tomatoes, garlic, Italian seasoning, and red pepper flakes. Let cook until most of the liquid from the tomatoes has cooked off, about 4 minutes, and then add the reserved squash. Cook and stir until most of the remaining liquid has cooked off, about 1 to 2 minutes more, increasing the heat if needed. Stir in 1/2 cup of the shredded cheese. There may be some liquid remaining in the pan.

Lightly coat a deep 8×8-inch baking dish or 2-quart casserole dish with nonstick spray. With a slotted spoon, scoop the squash mixture into the pan in an even layer, discarding any excess liquid (some in the pan is OK—just not too much). Bake, uncovered, for 20 minutes. Remove from the oven and sprinkle with the remaining 1/2 cup cheese, and then return to the oven and bake until the cheese melts, about 5 to 10 additional minutes. For an extra-golden-brown top, place the casserole under the broiler for a few minutes. Remove from the oven, sprinkle with parsley and/or basil, and let rest 5 minutes. Serve hot.

Ingredients:
2 whole spaghetti squash
1 to 2 tablespoons olive oil
½ teaspoon salt
½ teaspoon pepper
1 teaspoon dried basil
1 teaspoon dried oregano
½ teaspoon crushed red pepper flakes
2 cups marinara sauce
1 8 ounce ball fresh mozzarella, thinly sliced
2 tablespoons finely grated parmesan cheese, for sprinkling
fresh basil and oregano for sprinkling

Directions:
Preheat the oven to 425 degrees F. Line a baking sheet with foil and spray with nonstick spray.
Slice the spaghetti squash in half lengthwise and scrape out the sides. Brush the cut sides with olive oil. Place the squash cut-side down on a baking sheet. Roast for 25 minutes.
Remove the baking sheet and flip the squash over. Use a fork to scrape some of the squash up. Season the squash with salt and pepper. Sprinkle on some of the basil and oregano too.
Fill each squash with about ½ cup of marinara or Bolognese (your preference!). Lay the slices of mozzarella on top. Sprinkle on a bit more basil, oregano and the pepper flakes.
Return the baking sheet to the oven and bake the squash for another 15 to 20 minutes, until the cheese is golden and bubbly.
Sprinkle the squash with finely grated parmesan and fresh herbs and serve!

Ingredients
1 spaghetti squash
extra-virgin olive oil
sea salt and freshly ground black pepper

Directions:
Preheat the oven to 400°F.
Slice the spaghetti squash in half lengthwise and scoop out the seeds and ribbing. Drizzle the inside of the squash with olive oil and sprinkle with salt and pepper.
Place the spaghetti squash cut side down on the baking sheet and use a fork to poke holes. Roast for 30 to 40 minutes or until lightly browned on the outside, fork tender, but still a little bit firm. The time will vary depending on the size of your squash. I also find that the timing can vary from squash to squash.
Remove from the oven and flip the squash so that it’s cut side up. When cool to the touch, use a fork to scrape and fluff the strands from the sides of the squash.
