Keto Blue Cheese Dressing

Homemade Blue Cheese Dressing

Salads and wings are probably the first thing that come to mind, but I use this dressing way beyond that. Pour it over an iceberg wedge with bacon crumbles. Drizzle it on grilled steak. Dip buffalo cauliflower into it. Layer it on burgers with a little horseradish sauce for something different. I’ve even swapped it in where I’d normally use cilantro aioli as a dip for raw veggies and it works. Since it’s high in both fat and protein, it actually keeps me full way longer than most dressings. That matters when I’m grabbing a salad for lunch and don’t want to be hungry an hour later.

This takes 5 minutes. That’s it. You probably already have everything in your fridge and pantry right now. For almost no effort, you get a dressing that keeps in the fridge for up to a week. I make a batch every Sunday and grab it for lunches all week. You can control how chunky or smooth it is just by how long you stir. Keep mixing and press the crumbles against the bowl for something creamier, which also lets them release more of that sharp, tangy flavor into the base.

Store-bought versions are convenient, but they never taste the same. I’ve tried a lot of them. The homemade version has a brightness and tang that bottled dressing can’t match. Plus, you get to pick your own crumbles and adjust the consistency exactly how you want it. Once you’ve had fresh, it’s hard to go back. If you’re the type who likes creamy sauces in rotation, my alfredo sauce is another staple I keep on hand.

Is Store-Bought Dressing Keto?

Most store-bought versions are technically low in carbs, but the ingredient list tells a different story. I’ve checked dozens of labels, and most brands sneak in vegetable oils, added sugars, and preservatives that I don’t want in my food. Vegetable oil is inflammatory, so even if the carb count looks fine on paper, I skip them on keto. This recipe uses avocado mayo instead, which is a much healthier fat source.

The dressings in the refrigerated section at the grocery store tend to be cleaner with fewer preservatives, but you still need to flip the bottle and read the ingredients. Always check for added sugar, because it shows up in brands you wouldn’t expect.

Is This Cheese Low Carb?

Yes, and that’s one of the reasons I reach for it so often. A 1-ounce (28g) serving typically has just 0.7g net carbs. Some varieties made with buttermilk run a bit higher, so I always read the nutrition label before buying a new brand. For keto, I stick with crumbles that keep the carbs under 1g per ounce. Gorgonzola tends to be my go-to because it has a strong flavor without being overpowering, so I can use less and still get that punch.

Which Variety Should I Use?

I’ve made this with Gorgonzola, Roquefort, and Stilton, and they all work. The flavor profile shifts depending on what you pick. Gorgonzola is the mildest and what I reach for most often. Roquefort has a sharper, saltier bite that some people love (I find it can overpower the other flavors if I use too much). Stilton lands somewhere in the middle. Whatever you choose, make sure you’re buying actual crumbles or a wedge you can crumble yourself. The pre-crumbled bags at the grocery store work fine. I’ve used Trader Joe’s crumbles and they dissolve really well when you smash them into the dressing.

How to Store This Dressing

Keep it in an airtight container (I use a mason jar) in the fridge for 5 to 7 days. I wouldn’t freeze it. The dairy separates and you lose that creamy texture completely. Since this takes 5 minutes to make, I just mix up a fresh batch when I run out. The recipe only makes 1 cup, so it goes faster than you’d think.

If it’s gone bad, you’ll know. It gets a funky, sour smell that’s distinctly different from the normal tanginess.

Can I Skip the Mayo?

I use avocado mayo because it adds richness without the inflammatory oils in regular mayo. But if you’d rather skip it, sub in more sour cream or Greek yogurt. The flavor will be a little more tart, but the dressing still comes out thick and creamy. One of my readers, Kon, uses Greek yogurt instead of mayo and says it works great. I’ve tried it both ways, and I’d say the yogurt version is tangier with a slightly thinner consistency. Both are good options. If you want a totally different dipping sauce for your fridge, my Chick-Fil-A sauce is another easy one to keep on hand.
