Is this tomato sauce keto-friendly despite the canned tomatoes?

Yes, in moderation. Tomato sauce and stewed tomatoes do contain natural sugars, but the carbs are kept in check by the meat-heavy recipe. Each serving has only 4g net carbs, making it a great fit for a low-carb lifestyle.

Can I make this sauce dairy-free?

It already is dairy-free! The recipe uses no cheese or cream, so it's suitable for dairy-free keto.

How can I reduce the sodium content?

Use low-sodium tomato sauce and stewed tomatoes, and opt for lower-sodium pepperoni or replace with fresh sausage. Taste as you season with salt.

Ingredients

tablespoons olive oil
onion, chopped
cloves garlic, minced
pound lean ground beef
(29 ounce) cans tomato sauce
(14.5 ounce) can stewed tomatoes
/2 pound pepperoni sausage, sliced
green bell pepper, chopped
(4.5 ounce) can mushrooms, drained and chopped
/4 teaspoon garlic salt
/4 teaspoon salt
/4 teaspoon ground black pepper
/4 teaspoon onion powder
/4 teaspoon dried oregano
/4 teaspoon Italian seasoning

Instructions

Step 1

I start by warming olive oil in a skillet and gently cooking the onions and garlic until they turn soft and golden. That caramelization adds a depth of flavor that's hard to beat. While they cool, I brown the ground beef in a large pot, breaking it up as it cooks. Once it's nearly done, I stir in the onion-garlic mixture and let it mingle for a few minutes. In goes the tomato sauce and stewed tomatoes, brought to a boil then reduced to a gentle simmer. After 15 minutes, I fold in the pepperoni slices and chopped green pepper, covering the pot for a half-hour simmer that melds everything beautifully. Finally, the drained mushrooms, garlic salt, salt, pepper, onion powder, oregano, and Italian seasoning join the party. A last 10-minute simmer lets the herbs wake up. The result is a thick, meaty sauce that clings perfectly to any low-carb base.

Chef's Tip

One trick I rely on: browning the beef in batches ensures it gets a nice crust, not just steamed. That fond becomes the backbone of flavor.

Storage Tips

Refrigerate cooled sauce in an airtight container for up to 4 days. Gently reheat on the stove with a splash of water if it thickens too much. This sauce freezes beautifully—portion into freezer bags and lay flat for quick thawing.

Variation Tips

Swap pepperoni for crumbled Italian sausage for a spicier kick. For a vegetable boost, stir in wilted spinach or roasted eggplant cubes just before serving. Serve over zucchini noodles, spaghetti squash, or as a topping for keto meatballs—the possibilities keep it fresh.
