    This Keto Bacon Roasted Butternut Squash is an awesome side dish, it pairs perfectly with just about any protein for an unbeatable keto dinner.

    Keto Bacon Roasted Butternut Squash in a cast iron skillet

    Man Oh Man we love this Keto Bacon Roasted Butternut Squash, it's all you've ever want in a side dish. Yes, butternut squash is high(er) carb compared to other low-carb vegetables but see our explanation below to see why we think it's still a great option for ketogenic diets. Other than butternut squash soup, roasting butternut squash with bacon is our favorite way to utilize this winter squash.

    For this recipe, we're roasting the squash with bacon, brown erythritol (we use Swerve), Dijon mustard, garlic, and a few spices. Yum! Seriously, as the bacon renders the squash soaks up all of the delicious bacon grease and the outsides of the squash get a bit crispy as well. This is definitely one of our favorite keto side dishes for fall!

    Keep reading for the ins and outs of this recipe!

    Is butternut squash keto?

    Butternut squash can definitely be eaten on a keto diet. While winter squashes are higher carb than most vegetables they can still fit nicely into a low-carb high-fat diet. Our view is that vegetables pack tons of nutrients and we'd rather our carb sources come from nutrient-packed food than processed junk.

    There are about 13g net carbs per cup of butternut squash which makes it a fairly high-carb vegetable option. However, by pairing it with other very low-carb ingredients you can definitely make it work for a keto-friendly diet.

    That being said, to make this recipe work for a 10g net carb meal (this is what we try to stay under for all of our recipes to fit easily into everyone's diet) we would pair this with a grilled steak or broiled salmon.

    What should I serve this Roasted butternut squash with?

    See above, steak and salmon are my go-to's but any grilled or roasted meat dish would be fantastic.

    How do I cut a butternut squash?

    Ah, cutting butternut squash can be such a pain! If you're near a Trader Joe's I would highly suggest picking up a package of their pre-cut butternut squash for ease.

    If you would rather buy the whole squash here's how you cut it:

    1. cut off the ends - using a large chef's knife (no pairing or steak knives here for goodness sakes) trim ¼" off each end.
    2. peel - use a vegetable peeler to peel off the outside skin until you get to the bright orange flesh.
    3. cut in half - stand it on its large base and cut straight down the middle.
    4. remove the seeds - use a spoon to scoop out the seeds. If you want you can roast these just like you would pumpkin seeds!
    5. cut into slices - cut each squash half in half width-wise then cut into slices length-wise.
    6. cube - cut each slice into cubes.

    Yeah, see why we opt for pre-cut squash? Ha!

    Can I add other vegetables to this recipe?

    Brussels sprouts are also delicious with the butternut squash here. Just halve them and throw them into the mix. Please note that this will obviously change the nutritional information as well as the serving size.

    What is the nutritional information of this keto bacon roasted butternut squash recipe?

    As always, you can find the full nutritional breakdown including the carb count (total carbs and net carb counts) at the bottom of the recipe card. You can find the serving size/yield at the top of the recipe card. You should always double-check your specific ingredients as different brands' ingredients may have different values. This recipe has 9.1 grams of carbs (net) per serving.

      The recipe lists 2 tsp olive oil but the instructions don't say where to put it in. Do we toss the squash with it or mix it with the topping?

      Holy Cheese on a Cracker! That stuff was divine! A friend had given me a 10 oz bag of frozen butternut squash and I was looking for something different to make with it. I added about 1 cup of homemade pumpkin puree, some sliced garlic and fresh ginger. The whole casserole was eaten before the main dish! Thank you. We'll definitely make this again.

      Mine is in the oven at this moment! I didn't have bacon (who doesn't have bacon -lol) so I used cubed ham; added another tsp of olive oil to make up for the missing bacon fat I took a lesson from the commenter above and added a few grates of fresh ginger. I'm having my squash with a rib eye for tonight's dinner. I sure hope I love it -I do love the ingredients.

      Very delicious recipes! Little suggestion for prepping the squash.
      I cut the ends of with a chefs knife. then I cut it in to inch slices.
      I lay the slices on the cutting board and just cut off the outer parts.
      'then i take a grapefruit spoon and take the seeds out. This is all
      done in a few minutes without much effort.

      This was good. I didn't think I could have butternut squash on a low carb diet, but the bacon also fills up the volumn. This will be a repeat dish!

        Hi Frances! Unfortunately, that’s not how recipes work. Unlike a packaged food product that is made by a single company, recipes can’t provide reliable serving weights due to the fluctuations in how different people measure and cook. To get a reliable serving size you’ll need to weigh your final dish then divide by the number of servings. You can also simply eyeball 1/4th of the recipe. I hope this helps!

        If not low-carb you could use brown sugar, honey, or maple syrup. If low-carb, I would just leave it out as a regular granulated "sugar" wouldn't be the same as the brown erythritol.

      This recipe is absolutely scrumptious exactly as written! I made it exactly as described, except I see now that I probably should have chopped my bacon instead of just laying the half-slices across my squash. It doesn't matter, though, because it was phenomenal even without chopping it up. 🙂 USE THE SWERVE BROWN SUGAR. It is divine! You can find Swerve at tons of stores now, so spring for the good stuff and don't skip it because it is delicious! Also as a time saver, I bought already-cubed butternut squash from my local Fresh Market, and it was all ready to go when I got home. I used my brand-new Field Company 12" cast iron skillet and doubled this recipe. I will definitely make this winner again and next time will try it with chopping the bacon, and maybe making extra topping because it was gooooood stuff! 🙂 Thank you for a great recipe that is definitely making the rotation!

      Here's my spin on this recipe. In addition to the squash, my only other ingredients are olive oil, diced pancetta, paprika, diced red bell pepper. that's it! You need no other salt, no garlic, no sweeteners...keep it simple and fresh. I baked a medium cubed squash in a deep cast iron skillet for 45 min at 425. Heaven!

      My 8 year old son really wanted to buy a butternut squash at the store the other day. I gave in and started to hunt for a recipe. I’m always open to anything with bacon. After I managed to get into the squash and cube it, we made this recipe. The best, and I mean best recipe I’ve ever made with butternut squash!! We were fighting over the last piece! 😂
      This will be on our table at least 3 times a month! Thanks!

      Is the bacon supposed to be cooked before mixing it in? It didn’t say to, but our bacon didn’t come out crispy, it is super mushy and there is a ton of liquid.

      Amazing! Can't wait to make for Thanksgiving. I'm going to lower the oven temp slightly and watch roasting time carefully. The first time I made it following the directions some of it burned. Also, the bacon needs to be chopped, not just cut in half.
