Ingredients & Tools
For the Meatballs:
- 450 g ground beef (80/20 blend is ideal for juiciness)
- 110 g finely grated Parmesan cheese
- 1 large egg
- 2 cloves garlic, minced
- 1 tbsp dried Italian seasoning
- 1/2 tsp sea salt
- 1/4 tsp black pepper
- 2 tbsp olive oil (for frying)
For the Sweet and Sour Sauce:
- 120 ml sugar-free ketchup
- 60 ml rice vinegar (or apple cider vinegar)
- 2 tbsp soy sauce (or coconut aminos)
- 1 tbsp Worcestershire sauce
- 1-2 tbsp granulated erythritol or allulose (adjust to your preferred sweetness)
- 1 tsp grated fresh ginger
- 1/2 small onion, finely diced
- 120 ml beef broth
- 1 tbsp sesame seeds and sliced green onions for garnish
Tools: A large, oven-safe skillet is your best friend here, along with a mixing bowl, a small whisk, and a measuring set.
Notes: Don’t use extra-lean beef—the fat keeps meatballs moist. Fresh ginger and garlic are non-negotiable for best flavor.

Before You Start: Tips & Ingredient Notes
- Don’t Overmix the Meatball Blend. Use your hands and mix just until the ingredients are combined. Overworking the meat will make the final texture dense and tough instead of light and tender.
- The Right Pan Makes a Difference. A good, heavy-bottomed skillet ensures even heat distribution, which means your meatballs will brown beautifully without burning and your sauce will reduce to a perfect, glossy consistency.
- Taste Your Sauce Before Adding the Meatballs. This is your chance to adjust the balance. Want it more tangy? Add a splash more vinegar. A little sweeter? A pinch more erythritol. You’re the boss of your sauce.
- Grate Your Own Parmesan. The pre-shredded stuff often contains anti-caking agents that can prevent it from melting seamlessly into the meatball mixture. A quick grate from a block makes a noticeable difference in texture.
How to Make Sweet and Sour Meatballs
Step 1: Combine the Meatball Ingredients. In a large mixing bowl, add the ground beef, grated Parmesan, egg, minced garlic, Italian seasoning, salt, and pepper. Now, here’s the trick: use your hands to gently combine everything. You just want to mix until you no longer see streaks of egg or cheese. Overmixing is the enemy of a tender meatball, so a light touch is key. The mixture will be a bit soft, but that’s perfectly normal.
Step 2: Form the Meatballs. With slightly damp hands—this prevents sticking—roll the meat mixture into evenly sized balls, about one heaping tablespoon each. You should get around 18-20 meatballs. Aim for uniformity so they all cook through at the same time. Place them on a plate or a small baking sheet as you go. You’ll notice the texture is firm enough to hold its shape but still feels moist.
Step 3: Brown the Meatballs. Heat the olive oil in your large skillet over medium-high heat. Once the oil is shimmering, carefully add the meatballs in a single layer, working in batches if needed to avoid crowding the pan. You’re not cooking them through just yet; you’re just looking for a nice, golden-brown sear on all sides. This should take about 5-7 minutes total. The sizzle and the aroma at this stage is just… wonderful. Remove the browned meatballs to a clean plate and set them aside.
Step 4: Create the Sweet and Sour Sauce. Reduce the heat to medium. In the same skillet, using the delicious rendered beef fat and oil, sauté the diced onion until it becomes soft and translucent, about 3-4 minutes. Add the grated ginger and cook for another 30 seconds until fragrant. Now, pour in the sugar-free ketchup, vinegar, soy sauce, Worcestershire sauce, granulated sweetener, and beef broth. Use a whisk to combine everything, scraping up all those flavorful browned bits from the bottom of the pan. That’s pure flavor gold right there.
Step 5: Simmer and Glaze. Let the sauce come to a gentle simmer. You’ll see it start to bubble around the edges. Allow it to cook for about 2-3 minutes, stirring occasionally. This brief simmering helps the flavors meld and the sauce will begin to thicken slightly. The color will deepen to a rich, reddish-brown. This is when you should do a quick taste test and adjust any seasonings to your liking.
Step 6: Finish Cooking the Meatballs. Carefully return all the browned meatballs back to the skillet, nestling them into the sauce. Spoon some of the sauce over the top of each one. Reduce the heat to low, cover the skillet with a lid, and let it simmer gently for 8-10 minutes. This allows the meatballs to cook through completely and absorb all that incredible sweet and sour flavor. The sauce should look glossy and coat the back of a spoon.
Step 7: Garnish and Serve. Once the meatballs are cooked through (you can check by cutting one in half to ensure there’s no pink left), they are ready. Turn off the heat. Give everything one final gentle stir. Transfer to a serving platter and generously sprinkle with sesame seeds and sliced green onions for a fresh, colorful finish. The contrast of the green onions against the deep red sauce is just beautiful.
Storage & Freshness Guide
- Fridge: Cool completely, store in an airtight container for up to 4 days.
- Freezer: Freeze meatballs and sauce in a sealed container for up to 3 months.
- Reviving: Reheat gently on the stovetop with a splash of broth to loosen sauce.
Serving Suggestions
Complementary Dishes
- Cauliflower Rice Pilaf — The fluffy, neutral base of cauliflower rice is perfect for soaking up every last drop of the delicious sauce, and you can stir in some peas and carrots for extra color and texture.
- Simple Steamed Broccoli — Its mild, slightly bitter flavor provides a wonderful contrast to the rich, sweet, and tangy meatballs, making for a very balanced plate.
- Zucchini Noodles (Zoodles) — A quick sauté with a little garlic gives you a “pasta-like” experience that feels indulgent but keeps things firmly in the low carb zone.
Drinks
- Iced Green Tea with Lemon — Its clean, slightly astringent quality cuts through the richness of the sauce beautifully and cleanses the palate between bites.
- Sparkling Water with Lime — The effervescence is incredibly refreshing and helps balance the savory and sweet notes without adding any extra carbs.
- A Light Pinot Noir — If you’re enjoying a glass of wine, a fruit-forward Pinot Noir with low tannins complements the umami of the meat without overpowering the sauce.
Something Sweet
- Mixed Berry Parfait — A few fresh raspberries and blueberries layered with unsweetened whipped cream provides a light, fresh, and slightly tart finish that feels like a perfect ending.
- Dark Chocolate Square — Just one or two squares of high-cocoa, sugar-free dark chocolate offers a rich, bittersweet note that contrasts wonderfully with the meal you just enjoyed.
- Chia Seed Pudding — A make-ahead vanilla chia pudding is creamy and satisfying, offering a different texture and a subtly sweet flavor that doesn’t feel too heavy.
Top Mistakes to Avoid
- Mistake: Overcrowding the pan when browning. If you cram all the meatballs in at once, they’ll steam instead of sear. You’ll miss out on that crucial caramelized crust that adds so much depth of flavor. I’ve messed this up before too, and it makes a world of difference to be patient and brown in batches.
- Mistake: Skipping the taste test for the sauce. Sweeteners can vary in intensity, and your personal preference is key. Not tasting the sauce before adding the meatballs is a missed opportunity to make it absolutely perfect for your palate.
- Mistake: Using a sugary, non-low carb ketchup. This one seems obvious, but it’s the foundation of the sauce. Using a regular ketchup will completely derail the low carb nature of this dish, so double-check your labels.
- Mistake: Boiling the sauce after adding the meatballs. A gentle simmer is what you want. A rolling boil can make the meatballs tough and cause the sauce to reduce too quickly, potentially making it overly thick or even burning.
Expert Tips
- Tip: Bake your meatballs for a hands-off approach. If you want to avoid standing over the stove, you can bake the formed meatballs on a parchment-lined baking sheet at 200°C for 15-20 minutes until cooked through, then just toss them in the sauce you’ve made in a separate pan.
- Tip: Make a double batch of sauce. The sauce is so good you’ll want extra. Doubling it means you can have more to spoon over your sides, and it freezes beautifully for your next meatball craving.
- Tip: Add a pinch of red pepper flakes. For a subtle kick of heat that plays wonderfully with the sweet and sour notes, add a quarter teaspoon of red pepper flakes to the sauce when you add the other liquids.
- Tip: Let the meatball mixture rest. If you have an extra 10 minutes, cover the mixed meatball blend and pop it in the fridge before forming. This helps the Parmesan hydrate and the flavors meld, resulting in a more cohesive and flavorful meatball.
FAQs
Can I use a different type of ground meat?
Absolutely! A mix of half pork and half beef is classic and adds wonderful richness. You could also use all ground turkey or chicken, but keep in mind that leaner meats can result in a slightly drier meatball. To combat this, you might add an extra tablespoon of grated Parmesan or a splash of olive oil to the mixture to keep it moist. The flavor profile of the sauce is robust enough to pair beautifully with any of these options.
How do I store and reheat leftovers?
Let the meatballs and sauce cool completely before transferring them to an airtight container. They’ll keep in the fridge for up to 4 days. To reheat, the best method is gently on the stovetop over low heat with a splash of water or broth to loosen the sauce. You can also use the microwave, but heat in 30-second intervals, stirring in between, to avoid the meatballs becoming rubbery. The flavors are often even better the next day!
Can I freeze these sweet and sour meatballs?
They freeze exceptionally well! Place the completely cooled meatballs and sauce in a freezer-safe container or a heavy-duty zip-top bag. They’ll be good for up to 3 months. Thaw overnight in the refrigerator before reheating. I like to freeze them in individual portions for a quick and easy future meal. The texture holds up perfectly through the freezing and thawing process.
My sauce is too thin. How can I thicken it?
If your sauce hasn’t reduced to your desired consistency, don’t worry. The easiest fix is to mix a teaspoon of xanthan gum with a tablespoon of cold water in a small bowl to create a slurry. Whisk this into the simmering sauce and it will thicken up almost instantly. Be careful not to add too much, as a little goes a very long way. You can also just let it simmer uncovered for a few extra minutes to reduce further.
What can I use if I don’t have sugar-free ketchup?
You can make a quick substitute! Combine tomato paste with a little water to thin it out, then add a splash of vinegar and your preferred granulated sweetener to taste. Start with 3 tablespoons of tomato paste, 2 tablespoons of water, a teaspoon of vinegar, and a teaspoon of sweetener, then adjust from there. It won’t be exactly the same, but it will create a great tomato-based foundation for your sauce.
