Transform healthy spaghetti squash into a satisfying low-carb meal that delivers all the comfort of pasta without the guilt. This keto-friendly dish combines tender strands of squash with savory Italian sausage and melted cheese, creating a meal that satisfies both healthy eating goals and comfort food cravings.

After countless experiments with spaghetti squash, I've discovered that proper roasting technique creates the perfect pasta-like texture.

Essential Ingredients

  • Spaghetti Squash: 2-3 pounds for best yield
  • Italian Sausage: 85/15 for best flavor
  • Fresh Mozzarella: Low moisture variety
  • Parmesan: Freshly grated
  • Yellow Onion: Finely diced
  • Fresh Garlic: Minced just before using

Detailed Instructions

1. Squash Preparation:
Using sharp knife, carefully cut 2-3 pound spaghetti squash lengthwise. Scoop out seeds and membranes before baking. Drizzle cut sides with olive oil, season generously with salt and pepper. Place cut-side down on parchment-lined baking sheet. Bake at 400°F for 35-40 minutes until tender when pierced with fork.
2. Sausage Development:
While squash bakes, brown 1 pound Italian sausage in large skillet over medium-high heat, breaking into small pieces. Once browned, transfer to paper-towel lined plate using slotted spoon. In same skillet, cook diced onion in remaining fat until soft and edges are golden, about 5-7 minutes. Add minced garlic, cook 30 seconds until fragrant.
3. Sauce Creation:
Return sausage to skillet with onions and garlic. Add marinara sauce and Italian seasonings. Simmer 10-15 minutes until sauce thickens enough to coat back of spoon. Taste and adjust seasonings.
4. Squash Preparation:
When squash is done, let cool slightly. Use fork to gently scrape flesh into spaghetti-like strands, leaving ½-inch border in shell to maintain structure. Season strands with salt and pepper.
5. Assembly Process:
Mix squash strands with half the sausage mixture. Divide evenly between squash shells, top with remaining sauce. Layer with torn mozzarella and grated Parmesan. Broil 3-5 minutes until cheese melts and browns in spots.

Temperature Control

Monitor squash during final broiling - cheese can burn quickly. If top browns too fast while center is still cold, move rack lower and switch to regular bake setting. For reheating leftovers, cover with foil until last few minutes to prevent cheese from burning.

This healthy comfort food proves that nutritious eating doesn't mean sacrificing flavor. Whether serving for family dinner or meal prepping for the week, it delivers Italian flavors while keeping carbs in check. Remember, patience during preparation yields the best texture and flavor in the final dish.

Ingredients

→ For the spaghetti squash

01 1 small spaghetti squash about 1.5 -2 pound
02 1 spray coconut oil
03 sea salt

→ For the filling

04 1 tablespoon butter
05 2 tablespoons yellow onion peeled and finely chopped
06 1 pound ground mild Italian sausage (not in links)
07 2 cloves garlic crushed
08 1 cup tomato sauce
09 1/2 cup heavy whipping cream
10 1/2 teaspoon dried basil
11 1/4 teaspoon dried oregano
12 1/8 teaspoon red pepper flakes (optional)
13 1/4 teaspoon black pepper (or to taste)
14 1/4 teaspoon sea salt (or to taste)

→ For assembling

15 2 tablespoons parmesan cheese finely grated
16 1/4 cup mozzarella cheese finely grated

Instructions

Step 01

Preheat oven to 350º Fahrenheit. Cut squash in half lengthwise and discard the seeds.

Step 02

Spray squash lightly with coconut oil and sprinkle with sea salt. Place cut-side down on a baking sheet. Bake squash 35-40 minutes or until tender. Using my oven, 35 minutes makes the squash noodles al dente, and 40 minutes makes them more tender. Test doneness by inserting a fork. If the fork slides in easily, the squash should be tender. Remove from oven.

Step 03

While squash is baking, prepare the filling. Heat a large skillet over medium high heat. Add butter. When butter stops foaming, add the onion.

Step 04

Cook onion, stirring occasionally, until onion is just starting to brown and starts to become translucent. Add the ground sausage. Cook sausage mixture, stirring occasionally, until sausage is browned and cooked through. Drain and discard excess grease.

Step 05

Stir in garlic and cook for one minute. Add tomato sauce, whipping cream, basil, oregano, red pepper flakes, black pepper, and sea salt. Stir until sauce has thickened. Taste and adjust seasoning. Set aside.

Step 06

When squash has reached the desired level of tenderness, remove from the oven. Increase oven temperature to 400º Fahrenheit. Turn each squash half using tongs or oven mitts, so that they are on the baking sheet with the cut side up.

Step 07

Fill the squash halves with the sausage mixture, then sprinkle 1 tablespoon parmesan cheese and 2 tablespoons mozzarella cheese on top. Bake in 400º oven for about 5 minutes or until cheese has melted. To serve, cut each half into three pieces, or scoop the squash and filling out of the shell.

Notes

  1. Works for low-carb, ketogenic, gluten-free, grain-free, diabetic, or Banting diets
  2. 35 minutes makes al dente squash, 40 minutes makes it more tender
  3. Can be served by cutting halves or scooping out filling
