How to make Healthy Low Carb Mexican Stuffed Peppers

Step One: Cut and Par Cook The Peppers

Cut the bell peppers in half right through the stem. This will give you two even sides that lay flat. They’re perfect for filling! Next using a kitchen spoon and paring knife, scoop out the core, seeds and ribs from the inside of the pepper. Leave the stem intact though so the filling won’t fall out the sides! 

Indeed they can be cooked in only 20 minutes and it’s not magic, I just used the microwave! This gives them a head start. That way, they will already be par-cooked when you fill them and top them with cheese they only need another minute or so to melt the cheese. I used this same technique for my Vegetarian Stuffed Peppers and it worked like a charm! 

I don’t know if you’ve ever had a stuffed pepper and wondered why the pepper was undercooked, but the reason is that they probably skipped this step of pre-cooking the pepper!

  • Microwave: Take the peppers halves and set them in a microwave safe baking dish. Place them cut side down so they cook evenly. Add some water so they will steam. (PHOTO 1)
  • Cover: To microwave veggies and trap the steam use plastic wrap, but make sure to put a layer of parchment (or wax paper works in a pinch) over the food so the plastic doesn’t touch the food.
  • Precook The peppers: Microwave the peppers until they’re tender. Note the times in this recipe are based on a 1200 watt microwave, so you’ll need to adjust depending on the model you have.

Step 2: Brown The Beef:

The filling is made with ground beef, in a style that resembles taco meat. To cook it, just heat some oil in a large heavy skillet and add the beef. Break it up in the skillet as it browns the same way you would for chili or American Chop Suey.

Step 3: Onions and Mushrooms for Bulk:

Next, add in onions for flavor and finely chopped mushrooms to add more bulk to the servings but very little calories or carbs.

Step 4: Bloom the Spices:

Once the veggies are softened, add in the spices to bloom them in the hot pan. They’ll smell amazing!!

Step 5: Make it Saucy:

Then just add tomato puree to make them saucy!

Step 6: Stuff the Peppers 

Once the peppers are soft, and the filling is cooked, you’re ready to assemble them. 

  • Drain Peppers: First, carefully remove the plastic from the dish of peppers. There will be steam trapped inside, and it’s easy to get burned by it. Then tilt the water out of the pepper dish, and flip them cut side up.
  • Fill with Beef: Spoon the beef mixture into the peppers, dividing evenly.

Step 7: Top with Cheese and Cook The Peppers

  • Without covering them again (which would stick to the cheese) pop the dish back into the microwave and microwave them until they are nice and soft and the cheese is completely melted. This takes about two or three minutes! 
  • Note, they’ll be really hot when they come out of the microwave, so let them sit for a moment so you don’t burn your mouth. (You can browse on Zappos while you wait. I won’t judge.)

How To Reheat

Microwave: To reheat the leftover stuffed peppers place them on a microwave safe plate and reheat for about 2 minutes. They should be steaming hot and make sure they are hot all the way through by testing with a thermometer. 

Oven: To reheat them in the oven place them in an ovenproof baking dish and bake loosely covered with foil for about 20 minutes at 350 degrees. They should be steaming hot.

Description

These cheesy spicy Low Carb Mexican Stuffed Peppers come together in only 20 minutes for a totally delicious, keto-friendly and family friendly weeknight meal.


Ingredients

Units Scale
  • 3 large bell peppers, cut in half lengthwise and cored
  • 2 teaspoons coconut oil or avocado oil
  • 1 pound grass fed beef
  • 1 cup chopped red onion
  • 1 cup chopped white or crimini mushrooms
  • 1 tablespoon ground cumin
  • 1 tablespoon chili powder
  • 1/2 teaspoon ground chipotle chili
  • 1/2 teaspoon salt
  • 1/4 teaspoon cinnamon
  • 1/2 cup canned tomato puree
  • 4 ounces shredded sharp cheddar cheese
  • chopped fresh cilantro leaves for garnish, optional

Instructions

  1. Place the peppers, cut side down in a microwave-safe baking dish. Add 1 cup water to the baking dish. Cover with a layer of parchment or wax paper. Cover with plastic wrap. Microwave on high until the peppers are just starting to soften, 4 to 5 minutes. Carefully remove cover, drain off water and turn the peppers cut-side up in the baking dish.
  2. Meanwhile, heat oil in a large skillet over medium-high heat. Add beef and cook, crumbling with a wooden spoon until the meat is browned, about 5 minutes. Add onion and mushrooms and cook, stirring often, until the mixture is browning along the edge of the pan and the vegetables are softened, 4 to 6 minutes.
  3. Stir in cumin, chili powder, chipotle, salt and cinnamon and cook until fragrant, about 30 seconds.
  4. Remove from heat and stir in tomato puree.
  5. Fill the peppers with the meat mixture (about ½ cup per pepper half).
  6. Top with cheese, dividing evenly. Microwave the peppers in the baking dish, uncovered until the cheese is melted and the peppers are tender, 2 to 3 minutes. Serve warm with cilantro on top if desired.

Notes

Microwave Tip: This recipe was tested in a 1200 watt microwave. Adjust cooking times depending on your microwave oven.

Once the peppers have been steamed, carefully remove the plastic from the dish of peppers. There will be steam trapped inside, and it’s easy to get burned by it.
