Ingredients

For the Vegetarian Spaghetti Sauce

  • 3 tablespoon olive oil - divided
  • 2 pounds HAPPY LITTLE PLANTS® Plant-Based Ground - unseasoned
  • 2 teaspoon salt
  • 1 tablespoon Italian seasoning
  • 1 teaspoon dried basil
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon black pepper
  • 2 medium onions - diced
  • 5 cloves garlic - minced
  • 2 tablespoon tomato paste
  • 2 (28 ounce) cans crushed tomatoes
  • 1 (28 ounce) can tomato sauce
  • 1 cup water - plus more if needed
  • 2 tablespoon fresh parsley - minced

For the Twice-Baked Vegetarian Spaghetti Squash Boats

  • 2 medium spaghetti squash
  • 2 tablespoon olive oil
  • salt and pepper - to season
  • 6-8 cups prepared vegetarian spaghetti sauce
  • 2 cups mozzarella cheese - shredded

Instructions

For the Spaghetti Squash

  • Preheat oven to 400 degrees F and line a large baking sheet with parchment paper.
  • Scrub the squash clean and dry thoroughly. Cut the squash in half lengthwise using a stable knife. Scoop out the seeds and stringy bits and discard.
  • Drizzle the squash with olive oil and use a pastry brush (or your hands) to brush over the entire surface of the squash. Sprinkle with salt and pepper and place cut-side down on the lined baking sheet.
  • Place squash in the oven and bake for 45 minutes to 1 hour or until squash is tender when pierced with a fork.
  • When cool enough to handle, gently scrape out the squash with a fork to remove the flesh in long strands.

For the HAPPY LITTLE PLANTS® Plant-Based Ground

  • Place 2 tablespoons of oil in a large nonstick skillet.
  • Heat oil over medium heat for 2 minutes.
  • Add the ground meat alternative to skillet and break apart into pieces. Gently stir to lightly coat with the oil.
  • Cook, stirring occasionally until the product reaches an internal temperature of 165°F, as measured by a meat thermometer, about 10-12 minutes.
  • Add the salt, Italian seasoning, dried basil, onion powder, garlic powder, and black pepper to the cooking ground meat alternative. Mix well to combine and cook for an additional 1 minute before removing from heat. Set aside.

For the Vegetarian Spaghetti Sauce

  • Add the remaining tablespoon oil to a large saucepot over medium-high heat. Add the onion and cook for 5-7 minutes, or until soft and translucent, stirring often. Once softened, add the minced garlic and tomato paste and mix well to thoroughly combine. Cook, stirring continuously, for 1 minute.
  • Stir in the crushed tomatoes, tomato sauce, and water and add the cooked ground meat alternative back to the pot. Mix well to combine and bring to a low simmer. Reduce heat to medium-low, cover, and allow the sauce to simmer for at least 20 minutes.
  • Season with additional salt, pepper, and Italian seasoning as desired.

For the twice-baked spaghetti squash

  • Preheat oven to 350 degrees F.
  • Gently scrape the spaghetti squash strands from each squash half. Add approximately 1-2 cups of prepared vegetarian spaghetti sauce to squash boat and gently mix with the separated strands of squash. Repeat with all squash boats.
  • Divide the shredded mozzarella cheese between the squash boats. Cover the baking sheet and squash with foil, creating a tent to prevent the foil from touching the cheese.
  • Bake at 350 degrees for 15 minutes. Remove the foil tent and bake an additional 5-10 minutes, or until cheese is golden and bubbly.

Notes

  • Save time: by cooking the spaghetti squash and HAPPY LITTLE PLANTS® Plant-Based Ground the day before. Or, by simply adding your cooked meat alternative to your favorite store-bought pasta sauce.
