Sour Cream and Onion Seasoning Recipe: Bold Snack-Time Flavor for Dips and Chips

This dry blend captures the tangy, savory essence of classic sour cream and onion flavor without the mess. I developed it for snack enthusiasts who want that bold taste on chips, dips, or popcorn.

The key is balancing powdered buttermilk for creaminess with dried onion and garlic for depth. A touch of citric acid delivers that signature tang that makes this blend addictively bold.

Mix it up in 2 minutes and store it in an airtight container for up to 6 months. The flavors stay fresh and ready to transform any dish into a snack-time favorite.

Sprinkle it on roasted potatoes, mix it into sour cream for dip, or shake it over popcorn. The possibilities are endless.

Ingredients for Sour Cream and Onion Seasoning

Eight simple dry ingredients blend into that classic snack flavor you crave instantly.

The powdered buttermilk is non-negotiable here—Hoosier Hill Farm or Saco brands have the best texture. You’ll find them in the baking aisle or online. Don’t confuse it with buttermilk powder (same thing, different name). The dried onion flakes should be fine-cut, not those big chunky pieces. I grab mine from Penzeys or the bulk section at Whole Foods.

No powdered buttermilk? Dry milk plus a pinch of cream of tartar gets you close. Skip the citric acid if you must, but the tang won’t be as bright. Fresh onion powder works, but dried is more concentrated. The parsley is mostly for color—dried chives can swap in if that’s what you’ve got.

This blend stays fresh for 6 months in an airtight container (a mason jar works great). Keep it in a cool, dark place—no fridge needed. The flavors actually deepen over the first week, so make it ahead if you can.

Step-by-Step Instructions for Sour Cream and Onion Seasoning

Here’s the method I use to create this bold, tangy blend that’s perfect for chips, dips, and more.

Step 1: Combine the Dry Base Ingredients

In a medium bowl, add the 3 tbsp Powdered Buttermilk, 1 tbsp Onion Powder, 1 tbsp Garlic Powder, and 1 tsp Sea Salt. These are your foundational flavors, so ensure they’re evenly distributed.

Whisk these together until fully incorporated—this prevents any clumping and ensures every bite carries consistent flavor. The powdered buttermilk is what gives this blend its signature creamy tang, so don’t skimp on mixing it thoroughly.

Step 2: Add the Tangy and Sweet Elements

Next, sprinkle in the 1 tsp Citric Acid and 1 tsp Granulated Sugar. These two ingredients balance each other perfectly—the citric acid delivers that sharp, tangy kick, while the sugar softens the acidity just enough.

Stir gently but thoroughly to combine. You’ll notice the mixture takes on a slightly finer texture as the citric acid integrates. This step is critical for achieving that classic sour cream and onion zing.

Step 3: Fold in the Onion Flakes and Parsley

Add the 2 tbsp Dried Onion Flakes and 1 tbsp Dried Parsley to the bowl. The onion flakes provide the bold, savory bite, while the parsley adds a touch of freshness and a pop of color.

Use a fork to break up any larger pieces of onion flakes as you mix, ensuring they distribute evenly. The goal is a uniform blend where every pinch delivers the full spectrum of flavors—creamy, tangy, and savory.

Step 4: Store and Rest for Optimal Flavor

Transfer the seasoning to an airtight container. I like to use a small glass jar for easy shaking and storage. Seal it tightly to keep moisture out, which can cause clumping.

Let the blend rest for at least 30 minutes before using. This allows the flavors to meld together, creating a more cohesive and vibrant seasoning. For the best results, wait 24 hours—the flavors deepen and intensify over time, making it worth the wait.

Shake the container before each use to redistribute the ingredients, especially the finer powders that tend to settle at the bottom. This ensures every sprinkle is packed with bold, balanced flavor.

Essential Equipment for Great sour cream and onion seasoning

Mixing Bowls

I always reach for my stainless steel mixing bowls for seasoning blends—they’re durable, lightweight, and won’t absorb odors. A medium-sized bowl (about 2-3 quarts) gives you plenty of room to whisk without spills. My set from Winco has lasted me years of heavy use. 💪

Whisk or Fork

A small wire whisk is my go-to for blending dry ingredients evenly. The wires break up clumps of powdered buttermilk and distribute finer spices like citric acid perfectly. In a pinch, a fork works too—I use one when I’m mixing small batches on the go.

Storage Containers

For storage, I swear by 8 oz mason jars with tight-sealing lids. They keep moisture out and let you see the blend’s vibrant color. Ball or Kerr brands are my trusted choices. For larger batches, OXO Pop containers with their airtight seals work beautifully.

Measuring Tools

Precision matters with seasoning blends. I use stainless steel measuring spoons from Cuisinox—they nest together and won’t rust. For the powdered buttermilk, a tablespoon scoop makes quick work. Always level off your measurements for consistency.

Fine Mesh Sieve

If your dried onion flakes are too large, a fine mesh sieve helps break them into smaller, more uniform pieces. I run mine through a #20 mesh for perfectly sized flakes. This step ensures every sprinkle delivers balanced flavor without large chunks.

Labeling System

I label all my seasoning blends with the name and date using chalkboard labels and a permanent marker. It’s a simple system, but it prevents mix-ups. For this blend, I always add a
