Phew, it has been bizzeee around here in the Hunley house. We have finally settled into a pseudo routine with school, new babysitters, and a new preschool schedule. 

It takes a while to find that good groove, ya know? I know you know because we all know!

Something that has helped me transition into a new rhythm is preparing dinner early and using my Instant Pot as much as possible. 

By early, I’m talking like 1 or 2 pm. Sometimes, as early as 9! It may sound crazy, but truthfully, getting dinner made and out of the way really helps when 5:00 rolls around. 

 

 

However, there are some days that no matter how hard I try, I can’t get my act together. 

I’ve really come to rely on my Instant Pot, and even my Crock-Pot, the last several months on those particular days.

Obviously, I love my Instant Pot. After all, I did write a cookbook with 100 Instant Pot recipes! 

I had been wanting to make a keto Instant Pot spaghetti for a while so, I finally did!

Making Your Keto Spaghetti

When I was creating this recipe, I still had quite a bit of zucchini left to use up. I knew I didn’t want to spiral the zucchini because sometimes my kids whine about “green” food. Eye roll. 

So instead, I used my food processor to shred the zucchini into little matchsticks. This lets me “hide” the veggies a little better and makes for more even cooking! If you don’t have a food processor, you could grate the zucchini by hand, it will just take a few minutes longer. 

 

 

Once the zucchini was shredded, I sat it on top of paper towels in a flat even layer. Then, I topped them with more paper towels so all of the excess water would be absorbed while I went to work on the meat.

Since zucchini is a natural watery vegetable, there wasn’t any need to add extra liquid to the Instant Pot, with the exception of your spaghetti sauce.

One last thing worth mentioning, be sure to follow the instructions for layering the ingredients in your Instant Pot. It will all get mixed at the end but you don’t want to burn your spaghetti sauce on the bottom of the pot (it’s not fun to clean up).

Serving Your Keto Spaghetti Casserole

After your casserole is done cooking, and you’ve added your cheeses, give it a good stir to combine everything. Transfer it to a baking dish, any size will do, and top it with shredded mozzarella. Place the keto spaghetti under the broiler for just a couple of minutes so the cheese can melt. I like to let it rest for about 5 minutes before serving. 

A side of steamed or roasted broccoli and caesar salad can complete your keto spaghetti dinner.

Keto Instant Pot Spaghetti Casserole

Yield: 6 servings
Prep Time: 10 minutes
Cook Time: 10 minutes
Additional Time: 3 minutes
Total Time: 23 minutes

Ingredients

  • 2 medium zucchini, about 1/2 pound
  • 1 pound ground beef
  • 1.5 teaspoons salt
  • 1/2 teaspoon pepper
  • 2 garlic cloves, minced
  • 2 teaspoons basil, dried or fresh
  • 8 ounces sliced mushrooms
  • 1.5 cups low carb marinara sauce
  • 2 cups shredded mozzarella cheese
  • 1 cup ricotta cheese

Instructions

  1. Shred zucchini using a food processor or grate by hand. You should have a little over 2 cups of shredded zucchini. Lay on top of paper towels, in a flat even layer, and top with more paper towels. Press the paper towels to absorb the excess water. Let sit while you prepare the beef.
  2. Turn the Instant Pot to sauté mode. Once hot, add the ground beef. Cook until most of the pink is gone, about 2 to 3 minutes. Break up with a wood spoon as it cooks. Press cancel.
  3. Add the salt, pepper, basil, and minced garlic and stir.
  4. Add the shredded zucchini to the ground beef and stir to combine.
  5. Add the mushrooms on top then the marinara sauce. Do NOT stir.
  6. Close the lid and seal the vent. Cook on low pressure for 10 minutes. Quick/manually release the steam. Press cancel.
  7. Remove the lid and stir to combine. Add 1 cup of the shredded mozzarella and the ricotta cheese. Stir to combine until all liquid is absorbed and the mixture has thickened.
  8. Transfer to a baking dish (any size will do) and top with remaining shredded mozzarella. Place under the broiler for 3 to 5 minutes until the cheese is melted and bubbly.
  9. Let rest 5 to 10 minutes before serving.

Notes

Spiralized zucchini can work in place of teh shredded. After spiralzing your zucchini, cut into small pieces for even cooking.
