This creamy dressing transforms a simple bacon, lettuce, and tomato sandwich into a restaurant-quality meal. The tangy blend enhances every bite without overwhelming the classic flavors you love.
I developed this version to strike the perfect balance between creamy richness and bright acidity. It uses just a handful of pantry staples and comes together in 5 minutes.
The sauce clings beautifully to crisp lettuce and tomatoes while adding moisture to the bacon. It keeps well in the fridge for up to a week, making it perfect for meal prep.
Use it on sandwiches, as a dip for fries, or drizzled over grilled chicken. This is the missing element your BLTs have been waiting for.

The mayo and sour cream are the base here. Duke’s or Hellmann’s for mayo—avoid the sweet salad dressing style. Sour cream adds that tang, but full-fat Greek yogurt works in a pinch. I grab both at Kroger or Walmart (the store brand stuff is fine). The vinegar cuts through the richness—white vinegar keeps it neutral, but apple cider works too (just might look a little cloudy).
No Dijon? Yellow mustard at double the amount, but it’ll be milder. Swap honey for maple syrup or agave if you need it vegan. Garlic and onion powder are non-negotiable for that classic deli flavor—fresh minced garlic can work, but the powder blends in smoother. If it’s too thick, thin with a splash of buttermilk or milk.
Stays fresh in a sealed jar for 7-10 days. The flavors meld best after 24 hours, so make it the night before if you can. Perfect for sandwiches, but don’t stop there—dip fries, drizzle on burgers, or toss with potato salad (it’s versatile).
Why You’ll Love This Recipe
- Mix in Minutes: I just dump everything in one bowl—mayo, sour cream, a splash of vinegar—and stir. No chopping, no fuss.
- Tangy Sweet Kick: The Dijon and honey play off each other like they were made for it. Honestly, it’s the reason I keep making BLTs.
- Smear on Everything: This sauce isn’t just for bacon lettuce tomatoes—it’s my secret on burgers, wraps, even as a veggie dip.
- Keeps Like a Champ: I make a double batch because it stays fresh in the fridge for a solid week. Between us, it tastes even better the next day.
Step-by-Step Instructions for BLT Sauce
Here’s how I whip up this creamy dressing in minutes—simple, foolproof, and packed with flavor.
Step 1: Combine the Creamy Base
In a medium bowl, add the 0.75 cup Mayonnaise and 0.5 cup Sour Cream. I like to use full-fat versions here because they give the sauce that luxurious, velvety texture we’re after.
Whisk them together until completely smooth—no streaks of either should remain. This base is what makes the sauce rich and cling perfectly to every bite of your sandwich.
Step 2: Add the Tangy Elements
Next, pour in the 2 tbsp White Vinegar and 1 tbsp Dijon Mustard. The vinegar cuts through the richness, while the Dijon adds a sharp, slightly spicy kick that balances everything out.
Whisk again until fully incorporated. You’ll notice the mixture starts to thicken slightly as the mustard emulsifies with the base. This is exactly what we want.
Step 3: Sweeten and Season the Sauce
Now, drizzle in the 1 tbsp Honey. This smooths out the acidity from the vinegar and mustard, rounding out the flavors beautifully. I prefer honey here for its natural sweetness and subtle floral notes.
Add the 0.5 tsp Salt, 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, and 0.25 tsp Black Pepper. These seasonings add depth without overpowering the sauce. Whisk one final time until everything is evenly distributed.
Step 4: Chill and Let Flavors Meld
Transfer the sauce to an airtight container or jar. Cover and refrigerate for at least 30 minutes—this gives the flavors time to meld together. I’ve found that chilling also thickens the sauce slightly, making it even more perfect for spreading.
You can use it immediately if you’re in a hurry, but the flavor is much better after chilling. This sauce keeps in the fridge for up to 5 days, so feel free to make it ahead of time.
Pro Tips For Making Blt Sauce
- Chill Before Serving: Let the sauce sit in the fridge for at least 30 minutes after mixing. I learned this the hard way—it tastes bland at first, but the flavors meld into something way more balanced.
- Use Full-Fat Sour Cream: Skip the low-fat version; the extra richness actually changes the outcome and keeps the sauce from getting watery over time.
- Whisk, Don’t Stir: Vigorous whisking for about 20 seconds blends the honey and mustard fully into the mayo—otherwise you’ll get little pockets of sweetness instead of a smooth sauce.
- Taste Before Seasoning: The vinegar and mustard can vary in acidity, so add salt or extra honey only after tasting. I was skeptical until I tried it, but it prevents overdoing it.
Flavor Customization for This Recipe
Spicy Kick
Add ½ tsp cayenne pepper or 1 tsp sriracha to the base for heat. I love this with grilled chicken sandwiches. The spice balances the creaminess beautifully. 🌶️
Herb Infusion
Mix in 1 tbsp chopped fresh dill or 1 tsp dried tarragon for an herby twist. These herbs pair especially well with the tangy vinegar.
Fresh chives work too—just add 2 tbsp finely chopped at the end.
Smoky Depth
Replace the Dijon mustard with 1 tbsp smoked paprika and ½ tsp chipotle powder. This gives a BBQ-inspired flavor that’s amazing on burgers.
Citrus Brightness
Swap the white vinegar for 2 tbsp fresh lemon juice or lime. The citrus adds a zesty note that brightens up the sauce perfectly. 💛
I often add 1 tsp lemon zest for extra punch.
Sweet & Tangy
Increase the honey to 2 tbsp and add 1 tsp apple cider vinegar. This creates a sweeter profile that kids love on sandwiches.
For a fruity twist, blend in 2 tbsp finely diced pickles.
