Navigating the grocery store aisles or whipping up a batch of homemade salsa can be tricky for anyone on a ketogenic diet, where every carb counts. The primary challenge is avoiding hidden sugars, high-carb fruits, and thickening agents like cornstarch that are often found in commercial products. Fortunately, plenty of flavorful, low-carb alternatives exist that let you enjoy the fresh, zesty kick of salsa without compromising your ketosis.
Homemade Keto Salsas: Your Best Option
Making salsa from scratch is the most reliable way to ensure it's completely keto-friendly. By controlling every ingredient, you eliminate any hidden sugars or carb-heavy fillers. The foundation of any good keto salsa includes a base of tomatoes or tomatillos, peppers, onions, cilantro, and lime juice.
Keto Pico de Gallo (Salsa Fresca)
This uncooked salsa is a perfect example of a naturally low-carb option. The simple, fresh ingredients pack a punch of flavor with minimal carbs.
- Ingredients:
- 4 large ripe tomatoes, seeded and diced
- ½ finely diced red onion
- 1-2 finely chopped chili peppers (jalapeño or serrano)
- ½ cup fresh cilantro, chopped
- Juice of one fresh lime
- Salt and pepper to taste
 
Instructions:
- Combine all ingredients in a bowl.
- Mix gently to combine.
- For best flavor, let it chill in the refrigerator for at least 30 minutes to let the flavors meld.
Roasted Tomatillo Salsa (Salsa Verde)
For a smoky, tangy flavor, a roasted tomatillo salsa is an excellent low-carb choice. Tomatillos are naturally lower in carbs than many fruits and produce a vibrant, flavorful green salsa.
- Ingredients:
- 2 lbs whole tomatillos, husked and rinsed
- 1 cup assorted chili peppers (jalapeño, serrano)
- 1 clove garlic
- ¼ cup chopped cilantro
- Salt and pepper to taste
 
Instructions:
- Roast tomatillos and chili peppers on a baking sheet under a broiler until they are charred and softened. This usually takes about 5-8 minutes.
- Transfer roasted vegetables to a blender or food processor with garlic, cilantro, and seasonings.
- Blend until you reach your desired consistency. Serve warm or chilled.
Best Store-Bought Salsas for Keto
While homemade is always the safest bet, there are several store-bought options that are suitable for a keto diet, provided you check the nutrition label carefully. The key is to look for brands that do not use added sugars or cornstarch as thickeners.
- Herdez Salsa Casera: This widely available brand is known for its simple, traditional ingredients and low carb count. At just 1-2g net carbs per 2 tbsp serving, it's a solid choice.
- Mateo's Gourmet Salsa: Mateo's advertises no added sugar in its mild, medium, and hot varieties, with only 2g of net carbs per serving.
- Frontera Roasted Tomato Salsa: With just 1g net carb per 2 tbsp serving, this salsa is another good option for those who enjoy a roasted tomato flavor. Note that some recipes might use orange juice concentrate, so always check the specific product label.
- Good & Gather Thick & Chunky Salsa: Target's house brand offers a low-carb, thick and chunky salsa option with a clean ingredient list.

Important Considerations for Choosing Salsa on Keto
While the main ingredients in salsa—tomatoes, onions, and peppers—are generally fine in moderation, the potential for added sugars or other carb-heavy ingredients is a real concern. Here's what to look for when shopping or making your own.
- Read the Ingredients List: Always check the ingredients list for terms like "sugar," "high-fructose corn syrup," or "dextrose." Some brands also use cornstarch or modified cornstarch to thicken their salsa, which can increase the carb count.
- Watch Serving Sizes: A 2-tablespoon serving of salsa might only contain 2-4g of net carbs. However, it's easy to use more than one serving, and those carbs can quickly accumulate. Be mindful of how much you're consuming to avoid exceeding your daily carb limit.
- Beware of Fruit Salsas: Mango, pineapple, and other fruit-based salsas are generally not suitable for a keto diet due to their high sugar content. Even a small amount of fruit can add a significant number of carbs.
- Refrigerated vs. Shelf-Stable: Refrigerated salsas, like those from brands such as Fresh Cravings, often have fresher ingredients and fewer preservatives, but it's still crucial to check their labels for added sugars.
- Flavor Matters: The type of salsa matters. A simple, fresh pico de gallo will almost always be lower in carbs than a cooked, restaurant-style salsa. Roasting vegetables before making the salsa, as with salsa verde, can deepen the flavor without adding carbs.
How to Use Keto Salsa
Since traditional tortilla chips are off-limits, you'll need keto-friendly alternatives for dipping. Some popular options include:
- Keto Tortilla Chips: Many brands offer low-carb chips made from almond flour or other keto-friendly ingredients.
- Cheese Crisps: Baked or fried cheese crisps provide a savory, crunchy vehicle for your salsa.
- Pork Rinds: These are a classic keto chip replacement and pair surprisingly well with salsa.
- Vegetable Sticks: Sliced bell peppers, cucumbers, or jicama are perfect low-carb dippers.
- Topping for Meals: Use keto salsa as a topping for grilled meats, taco salads, or scrambled eggs to add flavor without extra carbs.
Conclusion
Yes, you can absolutely enjoy salsa while on a keto diet, but being mindful of your choices is key. For ultimate control and the lowest possible carb count, homemade salsas like pico de gallo or salsa verde are your best bet. If you opt for a store-bought version, always check the nutritional label for hidden sugars and starch thickeners. By selecting fresh ingredients or trusted low-carb brands and pairing them with keto-friendly dippers, you can add a burst of flavor to your meals without derailing your diet.
