This keto broccoli salad delivers cold crunch, creamy tang, and enough fat from bacon and mayo to keep you in ketosis.
The 30-minute chill after assembly is non-negotiable: without it, the dressing stays loose and the broccoli never mellows from the vinegar.
Raw florets hold their snap through day three, though a 60-second blanch softens the bite if you are eating at home.
Keto Broccoli Salad
A cold, crunchy, creamy side is what this is, and it fills more roles than I expected when I first started making it.
Weeknight dinners, potlucks, cookouts — it travels well and holds up on a plate in summer heat better than anything mayonnaise-based has a right to.
The 2–5 net carbs per serving (sources range from 2 to 4.9 depending on add-ins) means it actually fits a keto day without being a bowl of sadness.
I give it 30 minutes in the fridge after assembly, minimum. The chill time matters: the dressing tightens, the broccoli softens just slightly from the acid, and the whole thing becomes more than the sum of its parts.
A crunchy, dressed broccoli salad beats the usual cookout afterthought of bare greens with nothing on them. Now it’s the bowl I bring that disappears first, keto or not.

Micro Ingredients Organic Broccoli Powder is made from raw broccoli, finely milled into a smooth powder that's easy to scoop and mix into your favorite drinks and recipes.
Ingredients
Fresh broccoli holds up better than frozen once the dressing hits it, so 6 cups of florets from a firm head is what I reach for. Frozen broccoli turns limp and weepy, and a crunchy salad needs crunch.
Here is what goes in:
- 6 cups broccoli florets, cut small
- 1/2 lb bacon, cooked and crumbled
- 1 cup shredded cheddar cheese
- 1/4 cup diced red onion
- 1/3 cup sunflower seeds
- 1 cup mayonnaise
- 2 tablespoons apple cider vinegar
- 2 tablespoons low-carb sweetener (erythritol, monk fruit, or Swerve)
The sweetener amount is a starting point. Some blends run sweeter than others, so taste the dressing before it ever touches the broccoli.

32 fluid ounces of organic apple cider vinegar
16 fl oz of raw unfiltered organic apple cider vinegar
Method
- Whisk 1 cup mayonnaise, 2 tablespoons apple cider vinegar, and 2 to 3 tablespoons sweetener in a bowl. The monk fruit and erythritol blends work here, though any granulated keto-friendly sweetener dissolves fine. Taste and adjust; some like it sweeter, some sharper.
- Chop 6 cups broccoli into small, bite-sized florets. Raw keeps the crunch that makes this salad worth eating, but if you prefer it softer, blanch the florets 1 minute in boiling water, then plunge into an ice bath to stop the cooking. Drain well; watery broccoli dilutes the dressing.
- Combine the broccoli with 6 to 8 slices crumbled cooked bacon, 1/4 cup chopped red onion, 1 cup shredded sharp cheddar, and 1/4 cup sunflower seeds in a large bowl.
- Pour the dressing over and toss until everything is coated. The bowl looks too dry at first; keep folding and it comes together.
- Chill 30 minutes to 2 hours. The shorter time works if you are pressed, but the flavors settle in more deeply closer to 2 hours.
- Stir once more before serving. The seeds and cheese settle, and the dressing loosens as it sits.
Prep time runs 10 to 20 minutes depending on whether you cook the bacon fresh or use leftover. Yield is 4 to 10 servings; the wide range depends on whether this sits beside a burger or fills a lunch container.

Nutrition and Carbs
The macros on this salad land between 266 and 408 calories per serving, with net carbs clocking in at 2 to 5 grams depending on whose spoon you’re using.
That range matters, and it mostly comes down to how heavy your hand gets with the mayo and bacon.
What keeps it firmly in keto territory is the fat. The dressing builds its body from mayonnaise, and the bacon folds in more fat plus salt that makes the whole thing taste like something you actually want to eat.
Broccoli brings the fiber, which knocks the net carbs down from the total, and the little bit of sweetener in the dressing stays minimal enough not to tip the scale.
Portion size is where the honesty comes in.
One recipe might yield six cups at roughly 408 calories and 4.1 net carbs per cup. Another breaks the same batch into six equal servings and hits about 396 calories with 5 grams net carbs.
The difference is not the ingredients; it is how you divide them. If you are the type to fill a bowl rather than measure, your count climbs.
If you are serving it as a side beside a steak, you are probably fine. If this is lunch, eye your serving and adjust the rest of your day accordingly.

Raw or Blanched Broccoli
Raw broccoli holds its crunch through day three in the fridge, which makes it the safer bet for anything that sits out.
Blanched broccoli gives you a brighter green and a softer bite, closer to what you’d get at a deli counter.
I go raw when I’m hauling this to a potluck or cookout where it might linger on a table for a couple hours.
At home, where we’re eating it straight from the fridge with dinner, I’ll drop the florets in boiling water for maybe 60 seconds, then shock them cold.
That small step changes the whole salad, but either way works. The dressing and bacon do most of the talking anyway.

Substitutions and Variations
Greek yogurt can stand in for half the mayo if you want a lighter tang, though the dressing stays creamier with full-fat mayo.
Red onion adds bite, but green onions mellow things out for anyone who finds raw onion too sharp. Cheddar is the classic choice, yet feta or provolone work if that’s what sits in your deli drawer.
Sunflower seeds give the expected crunch, yet pecans, macadamia nuts, or even pine nuts swap in cleanly. For sweetness, stevia or Swerve replace erythritol, just start light, taste, and adjust, since each sweetener carries a different punch.
Omit the bacon and you have a vegetarian version; lose the cheese too and swap in vegan mayo, and the salad becomes fully dairy-free.
Each substitution shifts the nutrition, so the carb count and fat numbers you started with will need rechecking if you are tracking macros closely.

Storage and Make-Ahead
Leftovers hold 2 to 5 days refrigerated, and the salad actually improves after a few hours as the flavors settle in. The dressing can be mixed up to 3 days ahead and kept separate.
Once assembled, the salad stays crisp for about 24 hours before the broccoli softens and the seeds lose their bite. Stir before serving any leftovers to redistribute the dressing.
If you want to make this ahead, we recommend waiting until just before you eat to dress everything (otherwise things might get a bit soggy). Either way, the salad will keep for up to 5 days in the fridge.
— Delish
That separation trick buys you the full 5 days instead of watching the texture fade after one.
