Hi there! It’s Jessica Gavin, Certified Culinary Scientist and I’m excited to share this simple turkey bolognese with roasted spaghetti squash recipe with you. If you’re looking for a satisfying Italian dinner, yet want to sneak in some extra vegetables then this dish is for you. A hearty bolognese sauce packs in the protein and vegetables while the serving it on a bed of squash.

I’m a big fan of beef bolognese, but to lighten things up this version features ground turkey. The poultry nicely infuses all of the aromatic flavors of garlic, onions, and oregano while tenderizing from the acidity in the tomatoes. As the sauce cooks the flavors meld together making it hard to resist grabbing that extra spoonful to load on top of the squash.

Ground Turkey

Lean ground turkey meat is neutral in taste but develops a nice flavor when browning the surface in a hot pan. I first cook the meat separately to ensure there’s plenty of room to sizzle before removing and adding the vegetables so that the turkey doesn’t overcook and become dry in texture.

To further build the flavor base of the sauce, garlic, onions, carrots, and mushrooms are sauteed until fragrant and tender. I like to saute the tomato paste for about a minute before adding the crushed tomatoes to coax the natural sweetness out of the concentrate. I’m really picky about the type of canned tomatoes I use and have found that San Marzano or vine-ripened products from Italy give the most balanced and pronounced flavor.

Giving the sauce time to simmer intensifies the flavor in a short period of time. The acids in the tomatoes help to break down some of the proteins in the turkey, making for more tender and soft chunks of meat. As the moisture from the sauce gradually evaporates, the ingredients become more concentrated. The result is a thick and hearty bolognese that tastes even better the next day too if you’re meal prepping or just cooking extra for later.

Roasted Spaghetti Squash

Have you ever tried spaghetti squash? I recently became obsessed with the long strands that make a seamless substitute for wheat-based pasta. It’s really easy to prepare and cook spaghetti squash. For this recipe, I sliced them into rings and roasted them at 400 degrees until tender. This yields the longest strands by carefully separating the flesh with a fork.

You can also cut the entire squash in half if you’d like to eat your meal straight from the “boat.” Using this ingredient is a nice switch up from other low carb options like zucchini noodles and its grain-free too.

So grab a bowl, add in a pile of golden vegetables and top with a generous serving of bolognese sauce. Grating some aged Parmesan cheese and sprinkle with fresh parsley adds the finishing touches. You’ll love how you can twirl the squash noodles around your fork just like conventional spaghetti. This recipe is also great for using up any leftover roasted turkey breast. Just add in the shredded meat into the sauce for a quick and easy meal solution.

    Very good and healthy meal that could whip up with what we had around the kitchen. Loved the “rings” of spaghetti squash as a new way to cook rather than just halving the squash…cooked faster and was less watery. So filling and delicious.

  2. Omg this is so good. I had left over turkey and used that. Instead of water to thin out sauce used lo sodium chicken broth. Added more garlic. This dish is a keeper

  3. 5 stars
    This dish was really great. I omitted the carrots because I ran out, but followed everything else exactly and it was fabulous. Definitely will make again! Thanks for the delicious recipe.

  4. Thanks girl… u got me outta what’s for dinner jam… easy enough … used whatever I had on hand and added lots of seasoning to spice things up …

    I really enjoyed this straightforward tasty recipe. I had never used the roasting method of cutting the squash into 1 inch rounds before and found it very easy and now preferred over the “boat.” I roasted the squash for 40 minutes and prepped the sauce during that time frame. Simmered the sauce for 1 hour and would have let it go longer but the buttery squash was so tasty it would have been eaten up if we waited any longer!

  7. Just a tip, onions and garlic are always cooked
    before the meat. They sauté much better when they go in first.
