The Secret Is in the Sauce: Homemade Keto Marinara
Forget store-bought sauces packed with sugar and preservatives. This homemade marinara is vibrant, fresh, and completely keto-friendly. It starts with extra virgin olive oil and a base of sautéed onions and garlic. From there, crushed tomatoes meld with oregano, basil, and a hint of red pepper flakes for subtle heat.
Pro Tip: For the best flavor, use San Marzano tomatoes if you can find them. Their natural sweetness and low acidity make the sauce irresistibly good.
Ingredients You’ll Need
For the Marinara Sauce:
- ¼ cup olive oil
- ½ medium onion, finely chopped
- 4 garlic cloves, minced or pressed
- 2 cans (14 oz) chopped tomatoes
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- Pinch of red pepper flakes (optional but recommended)
- Salt and freshly ground black pepper, to taste
For the Keto Meatballs:
- 500g ground beef (ideally 80/20 for best texture)
- 2 eggs
- ½ teaspoon salt
- ½ teaspoon pepper
- 1 tablespoon fresh parsley, finely chopped
- 1 teaspoon garlic powder
- ½ cup grated parmesan cheese
How to Make Keto Meatballs in Marinara Sauce
1. Start with the Sauce
Heat olive oil in a large, deep skillet over medium heat. Add the onion and cook until soft and translucent—about 5 minutes. Stir in the garlic and sauté just until fragrant (about 1 minute—don’t let it burn!).
Add the canned tomatoes and gently mash with a wooden spoon. Stir in oregano, basil, red pepper flakes, salt, and pepper. Bring to a gentle boil, then reduce heat and simmer uncovered for 20 minutes, allowing the sauce to reduce and the flavors to develop.
2. Mix the Meatball Ingredients
In a large mixing bowl, combine the ground beef, eggs, salt, pepper, parsley, garlic powder, and grated parmesan. Use your hands (or a spoon if you prefer) to mix until just combined—don’t overwork the meat or the meatballs may turn out tough.
3. Form and Cook the Meatballs
Roll the mixture into meatballs about the size of a walnut. Once the sauce has simmered for 20 minutes, gently place each meatball directly into the pan, nestling them into the sauce. Cover, reduce heat to low, and simmer for another 20 minutes, or until the meatballs are fully cooked through and tender.
No browning needed—the meatballs cook right in the sauce, absorbing flavor and staying extra juicy.
What to Serve With Keto Italian Meatballs
These meatballs are filling enough on their own, but if you’re looking for side dish inspiration, here are some keto-friendly ideas:
- Zucchini noodles (aka zoodles)
- Shirataki noodles
- Cauliflower rice
- Sauteed spinach or kale
- Keto garlic bread (almond flour-based)
You can also turn them into meatball subs with low-carb buns or wraps, or serve them over mashed cauliflower for a hearty, comforting bowl.
Storage & Freezing Tips
One of the best things about this recipe is how well it stores.
- Refrigerator: Store leftovers in an airtight container for up to 4 days. Reheat gently on the stovetop or in the microwave.
- Freezer: Let the meatballs and sauce cool completely. Freeze in a sealed container or zip bag for up to 3 months. Thaw overnight in the fridge and reheat on the stove.
Tip: Freeze in individual portions for grab-and-go lunches or quick dinners.
Tips for the Juiciest Keto Meatballs
- Use high-fat ground beef for best flavor and moisture.
- Don’t overmix the meat—handle it just enough to combine the ingredients.
- Simmer gently—a low, slow cook keeps the meatballs tender.
- Fresh herbs elevate the flavor, but dried work in a pinch.
- Grate your own parmesan for better melt and richness (pre-shredded often contains anti-caking agents).
Variations to Try
Want to switch things up? This recipe is super adaptable.
- Make it spicier: Add more red pepper flakes or mix in chili powder.
- Go dairy-free: Use nutritional yeast instead of parmesan.
- Try ground turkey or chicken instead of beef for a lighter option.
- Add spinach or chopped veggies to the meat mix for extra nutrition.
- Stuff with cheese: Form meatballs around a cube of mozzarella for a gooey surprise.
