How to make Keto Bacon Roasted Butternut Squash: step-by-step guide
Cooking methods
Preparation steps
- Gather and measure all the ingredients required for this recipe.
- If your bacon slices are not already cut in half, slice them in half so that each piece is shorter.
- Thinly slice the garlic.
- If you would rather buy the whole squash, here's the process to cut it. Cut off the ends of butternut squash using a large chef's knife, and trim ¼" off each end. Use a vegetable peeler to peel off the outside skin until you get to the bright orange flesh. Cut in half, stand it on its large base, and cut straight down the middle. Use a spoon to scoop out the seeds. If you want, you can roast these just like you would pumpkin seeds! Cut each squash half in half width-wise, then cut into slices length-wise. Chop each slice into cubes.
Cooking instructions
- Preheat oven to 425°F (220°C). Place the butternut squash, chopped bacon, and sliced garlic in a large 10.5" cast iron skillet.
- In a small bowl, mix together the brown erythritol, olive oil, mustard, paprika, salt, and garlic powder. Sprinkle the mixture over the squash and transfer to the oven. Bake for 45 minutes until the bacon is crispy and the squash is tender. Serve immediately.
Chef's pro tip
The most common mistake when making this recipe is ending up with soggy bacon or burnt edges on the squash. To ensure crispy bacon, cut it into smaller pieces before mixing. If you notice the squash getting too browned before it's tender, cover the dish with aluminum foil during the baking process, then remove it for the last few minutes to achieve the desired balance of texture and flavors.

Kristin says
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?
Alex Lester says
Sorry about that! You mix it with the topping.
JC says
Whats the serving size?
Amy says
I saw the instruction for olive oil but not the paprika! I guess to put in topping
Janice G says
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.
castironketoadmin says
So glad you enjoyed this recipe Janice!
Helen says
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.
Cast Iron Keto says
Ohh fresh ginger sounds delicious in this! We must have missed the prior comment mentioning it, thanks for pointing it out again - we can't wait to try it! Thanks Helen 🙂
Russ says
Loved this! That Kanye for the great idea. We will be doing this again.
Michelle says
This tasted so delicious! The only modification I made was tossing the squash and bacon in the olive oil, brown sugar crumble.
Jessica Straczowski says
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.
Lisa says
Trying tonight. Can you use stevia instead? I don't have the other.
Nhj says
So easy. So yummy!
Carri says
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!
Jo says
Can't understand why sweetener is added, Butternut squash is pretty sweet anyway so I left it out and recipe was yum. Thank you

Hi there! Mine is in the oven at the moment, and it smells delicious! I also added dried rosemary. You give the Nutritiional Facts per serving, but please can you tell me how many oz/grams each serving is?
Cast Iron Keto says
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!
Amber Morgan says
Delicious! My husband and I both wee raving and said this is a new classic for our home. He wants to take the recipe hunting in the Utah mountains with him. He'll cook it in a Dutch oven. Yummy!!!!
Isobel says
Can I use frozen squash chunks for this recipe?
Cast Iron Keto says
You should be able to but it may be a bit mushy.
Emily says
What could you use in place of brown erythritol?
Cast Iron Keto says
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.
Brenda Mantelli says
This is so good only change I made was just a tbsp of golden monkfruit its what I had on hand. Thank you delicious!
Kathryn Evans says
Delicious. Easy to make and a winner.
Sabrina says
This side dish was so delicious & simple. The butternut squash was caramelized and had an amazing flavor. My whole family enjoyed it (kids included). Thank you for the recipe!
Tara says
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!
Summer says
I couldn’t find any brown erythritol where I live. Can i substitute it with something else?
Marc W. says
I always make butternut squash soup but this is my new favorite way to eat it. I especially liked the cast iron skillet idea made the squash nice and crispy and candied DELICIOUS
Dee Costanza says
What if I don't have a cast iron skillet - guess a sheet pan will have to work. I need to get a cast iron skillet sounds like.
Cast Iron Keto says
Hi Dee, any oven-safe pan will work.
marsha says
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!
Yolanda Andrea Kriel says
Absolutely amazing. The savoury of the bacon works wonderfully with the sweet of the brown sugar. This one is a keeper
Pat says
I love this! It's easy to make and worth every single bite.
Dj says
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!
Joan Pierce says
,y family makes it a real struggle to get them to eat vegetables. They love this recipe and even request it.
Anonymous says
Can you use a baking dish? I don't have a cast iron skillet.
Cast Iron Keto says
You can! Even a sheet pan will work.
Becky says
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.
Karen says
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.
