These keto stuffed onions are loaded with ground beef, aromatic herbs, sweet tomato and oozy mozzarella cheese.

How to Make It

Step 1

Peel the onions and slice off the very tops and bottoms. Carefully slice a thin wedge from each onion, just enough to be able to easily separate the layers.

Step 2

Add the onions to a large pan of boiling water and simmer for 10-12 minutes until tender.

Step 3

Preheat the oven to 400 degrees Fahrenheit.

Step 4

Drain the onions and set aside to cool. Whilst the onions are cooling, finely dice the tomato and add to a mixing bowl along with the beef, mozzarella, oregano, salt and pepper. Tear in the fresh basil and stir to combine.

Step 5

Once the onions are cool, carefully peel off three layers from each. Retain the remaining onion if you wish for another meal.

Step 6

Divide the beef mixture into 6 even meatballs and arrange in the center of each onion strip.

Step 7

Roll the onion tightly around each meatball, so the filling is secure inside.

Step 8

Arrange the stuffed onions seam side down on a shallow oven tray and drizzle with the olive oil. Transfer to the oven to roast for 28-30 minutes, spooning over the juices halfway through cooking. The beef should be cooked through and the onion golden and slightly caramelized.
