Ingredients for Blt Sandwich Sauce
Creamy mayonnaise and sour cream form the base of this tangy, rich sauce.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥚 | ¾ cup | Full-fat for best texture |
| Sour Cream 🥛 | ½ cup | Standard or full-fat variety |
| Lemon Juice 🍋 | 1 ½ tbsp | Freshly squeezed preferred |
| Dijon Mustard 🟡 | 1 tbsp | Smooth variety for tang |
| Garlic Powder 🧄 | ½ tsp | Not garlic salt |
| Onion Powder 🧅 | ½ tsp | Adds depth of flavor |
| Worcestershire Sauce 🍶 | 1 tsp | Adds umami complexity |
| Salt 🧂 | ¼ tsp | Fine grain for even distribution |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Sweet Paprika 🌶️ | ¼ tsp | For subtle smokiness |
The mayonnaise is critical here—Duke’s or Hellmann’s deliver the right creaminess and balance. Sour cream adds tang, so don’t skip it. You’ll find both at any grocery store, but check the dairy aisle for full-fat versions. Fresh lemon juice brightens everything up, and Meyer lemons (in season winter to spring) add a floral note that’s worth seeking out.
No sour cream? Plain Greek yogurt at a 1:1 ratio works in a pinch. Out of Dijon? Yellow mustard at half the amount keeps the tang without overpowering. The Worcestershire sauce adds depth, but if you’re avoiding it, soy sauce at half the quantity gets you close. Fresh garlic can replace the powder—use 1 small clove, minced, and adjust to taste.
This keeps beautifully in an airtight container. It’ll stay fresh in the fridge for 1 week—the flavors actually deepen over time. Not recommended for freezing, as the texture can separate. Stir well before each use to recombine the ingredients.

Step-by-Step Instructions for BLT Sandwich Sauce
This classic tangy spread comes together quickly with a few simple mixing steps.
Step 1: Combine the Creamy Base
In a medium mixing bowl, add the 0.75 cup Mayonnaise and 0.5 cup Sour Cream. I use full-fat versions for the richest texture, though standard will work in a pinch. Whisk the two together until completely smooth and uniform in color.
This base creates the creamy foundation for your sauce. The mayonnaise provides body and richness, while the sour cream adds a subtle tang that balances the other flavors perfectly.
Step 2: Add the Tangy and Umami Elements
To the creamy base, add the 1.5 tbsp Lemon Juice, 1 tbsp Dijon Mustard, and 1 tsp Worcestershire Sauce. Stir well after each addition to fully incorporate the ingredients.
The lemon juice brightens the mixture with acidity, the Dijon mustard adds a sharp tang, and the Worcestershire sauce introduces a deep umami complexity. You’ll notice the sauce start to take on a more vibrant, balanced flavor profile.
Step 3: Incorporate the Seasonings
Sprinkle in the 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, 0.25 tsp Salt, 0.25 tsp Black Pepper, and 0.25 tsp Sweet Paprika. Whisk thoroughly to distribute the spices evenly throughout the sauce.
These seasonings add depth and warmth. The garlic and onion powders provide savory notes, while the sweet paprika contributes a subtle smokiness. The salt enhances all the flavors, and the black pepper adds a gentle heat.
Step 4: Rest and Adjust Seasoning
Let the sauce rest for 10-15 minutes at room temperature. This allows the flavors to meld together fully. During this time, the sauce will thicken slightly as the ingredients hydrate.
After resting, taste and adjust the seasoning if needed. If the flavor seems flat, a pinch more salt might help. For more tang, add a splash more lemon juice. The sauce should have a balanced, creamy texture with a slight sheen.
Pro Tips For Making Blt Sandwich Sauce
- Chill Before Serving: After mixing, pop it in the fridge for at least 30 minutes—I learned this the hard way when my first batch tasted flat because the flavors hadn’t melded yet.
- Use Full-Fat Sour Cream: Skip the low-fat version; full-fat sour cream gives the sauce that rich, creamy texture that actually changes the outcome.
- Balance the Lemon: Start with half the lemon juice, taste, then add more if needed—too much can overpower the mayo and mustard, and I’ve ruined a batch by dumping it all in at once.
- Fresh Garlic Swap: If you’ve got 2 minutes, trade the garlic powder for 1 clove of fresh garlic, minced fine—sounds small, but it adds a brightness that powder just can’t match.
Best Sauces and Condiments for This Recipe
Classic BLT Sauce
This creamy, tangy spread is the perfect complement to your sandwich. The blend of mayonnaise and sour cream creates a smooth base that pairs beautifully with crisp bacon and fresh lettuce. 💛
Spicy Chipotle Twist
For a smoky kick, add 1-2 tsp chipotle powder or 1 tbsp adobo sauce from canned chipotles. This variation adds depth without overpowering the original flavors. Adjust to your heat preference.
Herb-Infused Version
Stir in 1 tbsp finely chopped dill or 1 tsp dried parsley for a fresh, aromatic touch. I love how the herbs brighten up the richness of the sauce. Fresh chives also work wonderfully.
Sweet and Tangy
Add 1 tbsp honey or maple syrup to balance the acidity with a touch of sweetness. This works especially well if you’re using the sauce as a dip for sweet potato fries or roasted vegetable sandwiches.
Avocado Lime
Blend in ¼ ripe avocado and 1 tsp lime zest for a creamy, zesty variation. This adds a vibrant green color and pairs perfectly with grilled chicken or fish sandwiches. 🌟
Storage Tip
All variations keep well in an airtight container in the fridge for 5-7 days. Stir before each use, as some separation may occur naturally. Avoid freezing, as it can alter the texture.

Frequently Asked Questions
Can I make this sauce ahead of time?
Yes! This sauce actually tastes better after 24 hours in the fridge as the flavors meld. Store it in an airtight container for up to 1 week. Stir well before using.
What can I use instead of sour cream?
Plain Greek yogurt works perfectly as a 1:1 substitute. It maintains the tangy flavor while adding a bit more protein. For a lighter option, use low-fat yogurt.
Why does my sauce taste too sharp?
Balance the acidity by adding 1 tsp honey or 1/2 tsp sugar. If it’s too tangy from the mustard, a pinch more salt can help round out the flavors.
Can I freeze this sauce for later?
Freezing isn’t recommended as it can cause separation. The texture may become grainy when thawed. It’s best made fresh and stored in the fridge.
