This hot bacon dressing leans into everything good about bacon. It is rich, savory, and just a little sweet with a tangy finish. Made while the bacon fat is still hot, it comes together quickly on the stovetop.

Spoon it over salads, roasted vegetables, or pasta for a classic, comforting dressing that’s best served warm.

Here’s Why This Hot Bacon Dressing Recipe Works

Built on bacon drippings: Real rendered fat is the foundation, giving this dressing its signature depth and richness.

Balanced tang and sweetness: White wine vinegar and a spoonful of sugar keep the fat in check.

Quick stovetop blend: The dressing comes together fast and you can blend it smooth with an immersion blender, or leave it chunky for more texture.

Make-ahead friendly: It keeps for a week in the fridge and reheats well.

Ingredient Notes

Bacon: Thick-cut works best for rendering plenty of fat and delivering deep, smoky flavor. Skip lean or pre-cooked slices, they won’t give you enough drippings. Need a foolproof method? Here’s how to cook bacon in the oven.

Bacon fat: This dressing is built on rendered bacon fat, not butter or oil. Measure ½ cup after cooking; save the rest for frying eggs or roasting vegetables.

White wine vinegar: Sharp but not harsh. The vinegar balances the fat and brings brightness. Apple cider vinegar works too.

Dijon mustard: Adds body and depth. Don’t substitute with yellow mustard, it’s too vinegary and flat.

Red onion: Finely chopped so it softens quickly. Shallots work too for a slightly milder bite.

Garlic: Just two cloves, quick-sautéed, no browning. You want fragrance, not bitterness.

Try spooning this dressing over roasted vegetables, like our Brussels sprouts with cranberries, for a bold, savory-sweet side.

Recipe Tips

Cook the bacon crisp: You want deep flavor and plenty of rendered fat.

Don’t brown the garlic: A quick 30 seconds is enough. Browning garlic turns it bitter fast.

Use a wide-mouth jar: A wide jar is easier for whisking and blending, and doubles as your storage container.

Blend while warm: It helps emulsify the dressing into a creamy pour.

Reheat gently: A quick microwave zap or a warm water bath is all it takes. Don’t simmer or it may break.

Serving suggestion: This dressing shines over wilted greens. Try it in our warm spinach salad with bacon dressing for the full classic.

Ingredients 

  • 8 slices thick-cut bacon, cut into ½-inch pieces
  • ½ cup reserved bacon fat, from the cooked bacon
  • ½ red onion, finely chopped (about ½ cup)
  • 2 garlic cloves, minced
  • ½ cup white wine vinegar
  • 2 tablespoons granulated sugar
  • 1 tablespoon Dijon mustard
  • ½ teaspoon salt
  • ¼ teaspoon ground black pepper

Instructions 

  • Place a small skillet over medium-high heat and fry the bacon until crisp, about 5 minutes. Use tongs or a slotted spoon to transfer the bacon to a paper towel–lined plate. Set aside for another use.
  • Carefully pour the bacon fat into a heatproof measuring cup or jar. Measure out ½ cup and return it to the skillet. Set aside any extra fat for another use.
  • Reduce the heat to medium, add the onion and garlic and cook for 30-45 seconds until the garlic is fragrant. Do not brown.
  • Whisk together the vinegar, sugar, Dijon mustard, salt, and pepper. Pour the mixture into the skillet and cook over medium heat until hot and bubbling.
  • Pour the hot dressing into a wide-mouth Mason jar or other heatproof container. Blend with an immersion blender until smooth and creamy, or leave it unblended for a chunkier texture.
  • If desired, crumble a few pieces of crisp bacon and stir them into the dressing. Toss with salad greens, vegetables, or pasta.

Notes

Storage: Refrigerate leftover dressing in a covered container for 7 days.
Reheating: Warm gently in the microwave or place the jar in a bowl of hot water until heated through, don’t boil.
Equipment tip: Use a wide-mouth, 2-cup jar or pitcher for easy blending, pouring, and storing.
Serving suggestion: Best served warm over spinach salads, roasted vegetables, or cooked grains.
