Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the meatballs:
1 lb ground beef
1/2 cup almond flour
1 large egg
2 cloves garlic, minced
1/4 cup finely chopped onion
1 tsp salt
1/2 tsp black pepper
1 tsp paprika
For the sauce:
1/2 cup sugar-free ketchup
1/4 cup apple cider vinegar
1/3 cup water
2 tbsp soy sauce or coconut aminos
1/4 cup powdered erythritol
1 tsp xanthan gum
Directions
Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper.
In a large bowl, combine the ground beef, almond flour, egg, garlic, onion, salt, pepper, and paprika. Mix until well combined.
Shape the mixture into small meatballs and place them on the prepared baking sheet.
Bake for 18–20 minutes or until fully cooked and browned.
While the meatballs are baking, prepare the sauce. In a saucepan over medium heat, combine ketchup, vinegar, water, soy sauce, and erythritol. Stir well.
Bring the mixture to a gentle simmer, then sprinkle in xanthan gum while whisking continuously to thicken the sauce.
Once the meatballs are done, transfer them to the saucepan and toss gently to coat in the sauce.
Let them simmer together for 2–3 minutes before serving.
You can switch the ground beef with ground chicken or turkey for a lighter option. Add chopped bell peppers or pineapple-flavored keto substitutes to enhance the sweet and sour profile. For a spicier kick, include a pinch of chili flakes or a dash of hot sauce in the sauce mixture. If you prefer a smoother texture, blend the sauce before adding the meatballs.
Storage/Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, warm the meatballs in a skillet over medium heat until heated through, adding a splash of water if the sauce thickens too much. You can also microwave them in short intervals, stirring in between. For longer storage, freeze for up to 2 months and thaw overnight in the fridge before reheating.
FAQs
Can I make these meatballs ahead of time?
Yes, you can prepare and bake the meatballs in advance, then store them separately from the sauce until ready to serve.
What can I use instead of almond flour?
You can use coconut flour, but reduce the quantity to about 1/4 cup as it absorbs more moisture.
Is this recipe fully keto-friendly?
Yes, all ingredients are low in carbs and suitable for a ketogenic diet.
Can I fry the meatballs instead of baking?
Yes, pan-frying works well and adds extra crispiness, but baking is easier and less messy.
How do I prevent the meatballs from falling apart?
Ensure the mixture is well combined and includes the egg, which acts as a binder.
Can I make the sauce thicker?
Yes, you can add a bit more xanthan gum, but do so gradually to avoid over-thickening.
What side dishes go well with this?
Cauliflower rice or sautéed vegetables pair perfectly with this dish.
Can I use fresh tomatoes instead of ketchup?
Yes, but you’ll need to cook them down and adjust seasoning to mimic the tangy flavor.
Is erythritol the only sweetener I can use?
No, you can use any keto-friendly sweetener like monk fruit or stevia blends.
Can I double the recipe?
Absolutely, just scale up the ingredients proportionally and use a larger baking tray if needed.
