The first time I made this for my wife, she called her mother. BLT pasta salad is one of those ideas that sounds like a food-trend gimmick until you actually eat it, and then you understand why it works. The crispy bacon. The sweet roasted tomatoes. The cool lettuce that wilts slightly when it hits the warm pasta. A tangy, creamy dressing that ties everything together like a Southern diner chef figured out a way to turn America’s greatest sandwich into a cookout side dish.
My Italian-American instincts tell me to make everything from scratch, but I respect American regional cooking for what it is. The BLT is a perfect sandwich built on three perfect ingredients. Pasta salad gives you a way to stretch those three ingredients into something that feeds twenty people for eight dollars. That’s resourcefulness. That’s American comfort food doing what it does best.
This BLT pasta salad is built on good bacon, tomatoes that have been treated with some respect (roasted or at minimum salted), and a proper dressing that includes both mayo and sour cream for balanced tang and richness. The pasta stays al dente. The lettuce goes in at the last minute so it stays crisp. And you serve it immediately after assembling because this is one pasta salad that doesn’t benefit from overnight storage.
Why This BLT Pasta Salad Works
- Bacon is rendered crispy then added last — soggy bacon in a pasta salad is a crime; crispy bacon folded in at serving maintains texture
- Tomatoes are roasted or salted — raw tomatoes release water into the dressing; roasted or salted tomatoes are concentrated and don’t dilute the salad
- Mayo and sour cream dressing — pure mayo is too heavy; sour cream lightens it and adds tang that balances the bacon fat
- Romaine added at the last minute — lettuce wilts quickly; add it right before serving so it stays crisp and fresh
- Serve same day — unlike Italian pasta salad, BLT pasta salad is best fresh; the lettuce and bacon both deteriorate overnight
Ingredients
For the Pasta Salad
- 1 lb rotini, penne, or farfalle
- 12 strips thick-cut bacon, cooked crispy and crumbled
- 2 pints cherry tomatoes, halved (or 1 lb tomatoes, diced and salted)
- 1 large head romaine lettuce, chopped
- 4 green onions, thinly sliced
- Fresh chives, chopped (for garnish)
For the BLT Dressing
- 1 cup mayonnaise (full-fat)
- ½ cup sour cream
- 2 tablespoons red wine vinegar or apple cider vinegar
- 1 tablespoon sugar or honey
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon Dijon mustard
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
- 2 tablespoons reserved bacon drippings (optional but outstanding)
Instructions
Step 1: Make the Dressing
Whisk together mayonnaise, sour cream, vinegar, sugar, garlic powder, onion powder, Dijon, salt, and pepper. If using bacon drippings, whisk them in — the warm fat emulsifies into the mayo dressing and adds a smoky, porky depth that takes the dressing from good to outstanding. Taste and adjust: more vinegar for sharper, more sugar if too sharp, more salt if flat. Refrigerate until needed.
Step 2: Cook the Bacon
Lay bacon in a cold skillet. Start over medium heat and render slowly for 8–10 minutes until deeply crispy. Starting cold renders the fat before the outside burns. Remove to paper towels to drain. Crumble when cool. Reserve 2 tablespoons of drippings for the dressing if desired. Bacon can be cooked up to 24 hours ahead and stored at room temperature in an airtight container.
Step 3: Cook and Cool the Pasta
Bring a large pot to a boil. Salt it well. Cook pasta to firm al dente. Drain and rinse briefly with cold water — for cold pasta salads, a quick cold rinse stops cooking and cools the pasta quickly without making it gummy. The cold rinse is the one exception to the “never rinse pasta” rule — for cold dressed salads, a brief rinse is correct. Cool completely.
Step 4: Prepare the Tomatoes
If using raw cherry tomatoes: halve and salt lightly 10 minutes before assembling. The salt draws out excess water so it doesn’t dilute the dressing. Pat dry with paper towels before adding. For best results, roast cherry tomatoes at 400°F for 15 minutes with olive oil, salt, and a pinch of sugar — the concentrated sweetness is incredible in this salad.
Step 5: Assemble and Serve Immediately
In a large bowl, combine cooled pasta, green onions, and three-quarters of the dressing. Toss to coat. Add the tomatoes and toss gently. Right before serving: add the romaine and two-thirds of the bacon. Toss once more. Plate and top with remaining bacon, chives, and a final drizzle of dressing. Serve immediately. The lettuce and bacon are best in the first 30 minutes.
Chef’s Tips & Common Mistakes
- Never add lettuce to pasta salad you’re making ahead — lettuce wilts within an hour and turns the salad soggy; always add it right before serving
- Bacon drippings in the dressing — this is the upgrade move; the smoky fat in a mayo dressing takes the whole thing to another level
- Cold rinse is correct for this salad — unlike Italian pasta salad where you dress hot, BLT pasta salad uses a cold, mayo-based dressing; cool pasta completely first
- Salt the tomatoes — even 10 minutes of salting pulls out the water that would otherwise run into the dressing; pat dry before adding
- Reserve some dressing for serving — pasta absorbs dressing as it sits; always hold back some to add right before serving so it looks and tastes fresh
- Serve within an hour of assembly — this is a same-day salad; plan accordingly
Variations
- Ranch BLT Pasta Salad: Substitute ranch dressing for the mayo-sour cream base — the BLT on a ranch dressing pasta, related to ranch pasta salad
- Italian BLT: Use the Italian pasta salad dressing with bacon, tomato, and arugula instead of romaine
- BLAT (with Avocado): Add diced avocado right before serving — the creamy fat of avocado plays against the crispy bacon beautifully
- Warm BLT Pasta Salad: Use the pasta warm, add wilted arugula instead of crisp romaine, and make the dressing more like a warm bacon vinaigrette — a hybrid between pasta salad and warm pasta dish
- Southwest BLT: Add corn, black beans, and pepper jack cheese — see southwest pasta salad for the flavor profile applied to the same salad base
- Caprese BLT: Add fresh mozzarella and basil alongside the bacon and tomatoes — the bridge between a BLT and a caprese pasta salad
Storage & Reheating
Refrigerator: Store pasta and dressing separately if making ahead, up to 2 days. Do not store with lettuce or bacon mixed in — assemble at serving time only.
Make-Ahead Components: Cook bacon up to 24 hours ahead and store at room temperature. Make dressing up to 3 days ahead and refrigerate. Cook pasta the morning of and refrigerate. Assemble right before serving.
Assembled Salad: Eat within 1–2 hours for best texture. After that, the lettuce wilts and the bacon softens.
Freezer: Not recommended under any circumstances.
Frequently Asked Questions
What pasta shape works best for BLT pasta salad?
Rotini is the best choice — the spirals hold the creamy dressing in their grooves. Farfalle (bow ties) makes for a visually appealing presentation. Penne works. Avoid long pasta — lettuce and bacon don’t integrate well with spaghetti or linguine. See Italian pasta salad for the rotini reasoning applied to a different flavor profile.
Can I use turkey bacon?
Yes, though the flavor is noticeably milder and the rendering technique is different. Turkey bacon doesn’t produce useful drippings, so the bacon-drippings-in-dressing upgrade isn’t available. Crisp it in a dry pan over medium heat. The texture will be slightly different but the concept works.
How do I keep the salad from getting watery?
Three things: salt and drain the tomatoes before adding; add lettuce at the last possible moment; keep the dressing slightly more viscous than necessary. The water in the tomatoes and the wilt-water from the lettuce are the two main sources. Managing both keeps the dressing creamy and the salad from pooling liquid at the bottom.
Can I make a lighter version of the dressing?
Greek yogurt in place of sour cream — slightly more tang, fewer calories, same consistency. Light mayo works but produces a thinner dressing; add an extra spoonful of Dijon to add body. Avocado blended into the dressing gives a naturally rich, creamy result with healthier fat than mayo — related to the BLAT variation above.
Can I use sun-dried tomatoes instead of fresh?
Yes — oil-packed sun-dried tomatoes have concentrated sweetness and don’t release water into the dressing. They’re an excellent alternative, especially in winter when fresh tomatoes are mediocre. Use about ½ cup, roughly chopped. Related: the southwest pasta salad uses corn and black beans as the vegetable base and is another way to avoid the watery-tomato problem.
