Simple Red Wine Meat Sauce Spaghetti Squash Bake
This simple red wine meat sauce spaghetti squash bake is rich, cozy, and full of classic Italian-inspired flavor. It has everything you want in a comforting baked pasta-style dinner, but it is made with tender roasted spaghetti squash instead of noodles. The result is a grain-free, gluten-free meal that still feels hearty, satisfying, and deeply flavorful.
The first time making a homemade red wine meat sauce can feel a little intimidating, but this recipe keeps the process simple and approachable. Garlic, onion, carrots, and celery create a savory base, while grass-fed beef, marinara sauce, Italian seasoning, and dry red wine simmer together into a sauce that tastes warm, balanced, and delicious. As it cooks, your kitchen fills with the kind of aroma that makes dinner feel special before it even reaches the table.
This spaghetti squash bake is perfect for a weeknight dinner, but it also works beautifully when you are craving a lighter Sunday-style pasta meal. It is naturally gluten free and grain free, and it can be made dairy free by using a dairy-free or vegan mozzarella-style cheese on top. If you prefer traditional mozzarella, that works well too.
One of the best parts of this recipe is its versatility. The red wine meat sauce is delicious layered with spaghetti squash, but it can also be used in other meals. Serve it over your favorite pasta, spoon it over roasted vegetables, use it in a lasagna-style bake, or enjoy it on its own with a simple side salad. The sauce is rich enough for comfort food cravings, yet the spaghetti squash keeps the full dish feeling light and balanced.
Using quality beef makes a noticeable difference in the final flavor and texture of the sauce. Grass-fed beef is used here, and it pairs beautifully with the sweetness of the carrots, the savory depth of the onion and garlic, and the acidity of the marinara. The red wine adds another layer of richness and helps the sauce taste like it has been simmering longer than it actually has.
If you are looking for an easy healthy dinner idea, a low-carb pasta alternative, or a cozy grain-free casserole, this red wine meat sauce spaghetti squash bake is a recipe worth keeping in your regular rotation. It is simple enough for a busy evening, flavorful enough for guests, and comforting enough to satisfy a baked pasta craving without needing traditional noodles.

Description
An easy, flavorful weeknight dinner made with roasted spaghetti squash, a simple red wine meat sauce, and melty mozzarella. This grain-free spaghetti squash bake is comforting, hearty, and lighter than a traditional baked pasta dish.
Ingredients
- 1 spaghetti squash, precooked and shredded with a fork
- 3 tbsp olive oil
- 2 cloves garlic, minced
- 1/4 yellow onion, finely diced
- 2 large carrots, diced
- 2 celery stalks, diced
- 1 lb grass-fed beef
- 1 tbsp Italian seasoning
- 1 24-ounce jar marinara sauce
- 1/2 cup dry red wine
- Mozzarella, thinly sliced
Instructions
- Prepare the spaghetti squash first. Slice it in half, drizzle it with olive oil, and roast at 400°F until tender, about 35 to 45 minutes. Once it is cool enough to handle, use a fork to scrape the flesh into spaghetti-like strands. While the squash roasts, begin making the red wine meat sauce.
- Heat a large skillet over medium heat. Add the olive oil, then reduce the heat slightly and add the minced garlic and diced onion. Sauté until the onion is soft and translucent, about 3 to 5 minutes.
- Increase the heat back to medium. Add the diced carrots and celery to the skillet, then sauté until the vegetables begin to soften, about 5 minutes.
- Add the grass-fed beef and Italian seasoning. Break up the beef with a spatula as it cooks. Continue cooking until the beef is fully cooked through and no longer pink, about 7 to 10 minutes.
- Reduce the heat to medium-low. Stir in the marinara sauce and let the mixture simmer for 10 minutes, stirring occasionally so the flavors can come together.
- Stir in the dry red wine and simmer for another 10 minutes. The sauce should become richer, deeper, and more flavorful as it cooks.
- Add half of the sauce to a 9-inch baking dish. Layer the shredded spaghetti squash over the sauce, then spoon the remaining sauce on top. Finish with thinly sliced mozzarella. Return the dish to the oven at 400°F and bake until the cheese is melted, about 7 to 10 minutes. If desired, turn on the broiler for 2 to 4 minutes to lightly brown the cheese, watching carefully so it does not burn. Serve warm and enjoy.
Notes
For a dairy-free version, use a dairy-free or vegan mozzarella-style topping. Regular mozzarella can also be used if dairy is part of your diet.
The red wine meat sauce can be made on its own and used in other meals, making it a versatile recipe for meal prep or simple dinners throughout the week.
