Step‑by‑Step Instructions for Spaghetti Squash Carbonara Step 1: Preheat Oven Begin by preheating your oven to 400°F (200°C). This temperature is just right for roasting the spaghetti squash, giving it that tender texture you’ll love. Once the oven is ready, you can move on to preparing your squash. Step 2: Prepare Squash Slice the spaghetti squash in half lengthwise and scoop out the seeds using a spoon. Place the squash cut-side down on a parchment-lined baking sheet. Bake it in the preheated oven for about 30 minutes. When done, the flesh should be tender and easily shredded into strands with a fork, providing the perfect base for your carbonara. Step 3: Cook Bacon While the squash is roasting, heat a large skillet over medium heat and add the chopped bacon. Cook it until it’s crispy, which should take about 5-7 minutes. Once it’s golden brown, remove the bacon from the skillet and set it aside, leaving the rendered grease in the pan for added flavor in your spaghetti squash carbonara. Step 4: Cook Chicken In the same skillet with the bacon grease, add the boneless skinless chicken thighs. Season them with Italian seasoning, sea salt, and pepper. Cook for about 12 minutes, flipping halfway through, until the chicken is golden brown and cooked thoroughly. Once done, remove the chicken, let it rest briefly, and then slice it thinly for easy inclusion in the dish. Step 5: Make Sauce In a mixing bowl, whisk together the almond milk, chicken broth, arrowroot starch, garlic powder, and a pinch of salt. This mixture will form the creamy, dairy-free sauce for your spaghetti squash carbonara. Make sure there are no lumps in the mixture as you whisk it until smooth and combined. Step 6: Combine All Ingredients Once the spaghetti squash is ready, use a fork to scrape out the strands and add them to your skillet with the reserved bacon grease. Pour the creamy sauce over the squash along with the sliced chicken and stir well, cooking for about 3-4 minutes. This allows the sauce to thicken and coat the spaghetti squash beautifully. Step 7: Finish Dish Finally, add the spinach to the skillet and stir until it wilts, which should only take about 1-2 minutes. Once the spinach is vibrant and tender, mix in the reserved crispy bacon. For extra creaminess, you can sprinkle in some optional Pecorino Romano or Parmesan cheese if desired. Serve this delicious spaghetti squash carbonara warm, garnished with fresh parsley for a touch of color and flavor. Expert Tips for Spaghetti Squash Carbonara Perfectly Cooked Squash: Ensure spaghetti squash is tender but not mushy; test with a fork before removing from oven to achieve ideal texture.

Spaghetti Squash Carbonara Recipe FAQs What should I look for when selecting spaghetti squash? When choosing spaghetti squash, look for a firm, symmetrical shape with a vibrant yellow color. Avoid any squash with dark spots or blemishes, as these may indicate overripeness. A good spaghetti squash should feel heavy for its size, suggesting it’s filled with moisture and flavor. How should I store leftovers of spaghetti squash carbonara? Store any leftovers in an airtight container in the refrigerator for up to 4 days. Make sure the dish has cooled completely before sealing to maintain the best texture and flavor. You can also safely reheat them on the stovetop or in the microwave, but be careful not to overheat to prevent the spaghetti squash from becoming mushy. Can I freeze spaghetti squash carbonara? Absolutely! To freeze spaghetti squash carbonara, let it cool completely, then transfer it to an airtight container or freezer bags, ensuring to remove as much air as possible to prevent freezer burn. It can be stored this way for up to 3 months. When you’re ready to enjoy it, thaw overnight in the refrigerator before gently reheating. What if my sauce turns clumpy? If your sauce turns clumpy, it’s often due to the arrowroot starch not being whisked in thoroughly. To prevent this, mix the starch with the liquid until smooth before adding it to the skillet. If clumps do form, try whisking rapidly as it heats or using an immersion blender to purée the sauce back into a creamy consistency before combining.
