You’ve probably heard of the famous Bloomin’ onion from Outback Steakhouse, right? Our keto beef stuffed onion is a healthy, non-breaded way to enjoy onions while sticking to your low-carb needs.

Onions are one of the best low-carb veggies you can eat. They are an excellent source of vitamin C, fiber, and folic acid. They also have a high protein ratio and contain calcium and iron. 

The type of fiber found in onions is special because they are prebiotic fibers. This type of fiber fuels the good bacteria in your gut to enhance the health of your microbiome.

Onions are also an excellent source of an antioxidant called quercetin, which has been shown to reduce inflammation and boost immunity (1). One study found that quercetin helps protect tissues against damage caused by drug toxicity (2).

Additional research shows that quercetin may possess anti-cancer benefits due to its ability to inhibit certain cytokines (3). You can increase the bioavailability of quercetin by adding more vitamin C to your diet. 

Onions have been called a “global benefit to health” by authors of one study (4). If you buy the red or purple kind, then your onions will also contain anthocyanins, which is another type of antioxidant with disease-fighting potential.

Our recipe also calls for beef, which contains high-quality protein and minerals that your body needs to drive enzyme processes. The bacon will add some fat and more protein so it helps build and repair tissues throughout your body.

Parmesan tops the protein pyramid and it is considered a low-lactose kind of food. Then we add spices, such as parsley, garlic powder, and dried basil, that are high in vitamins A, C, and K, as well as calcium, flavonoids, potassium, copper, manganese, and magnesium. 

Together, these beef and onion balls provide a complete meal with all the nutrients you need to fuel your low-carb diet!
