Ingredients for potato corner sour cream and onion powder
Five simple ingredients transform into the iconic Potato Corner flavor you crave for snacks or mashed potatoes.
| Ingredient | Amount | Notes |
|---|---|---|
| Onion Powder 🧅 | 3 tbsp | Fine grind for even distribution |
| Garlic Powder 🧄 | 1 tbsp | Freshly ground preferred |
| Powdered Nonfat Milk 🥛 | 2 tbsp | For creamy dairy notes |
| Granulated Sugar 🍚 | 1 tbsp | Balances sharpness |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Coarse grain preferred |
| Dried Parsley Flakes 🌿 | ½ tsp | For fresh green finish |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground for heat |
| Monosodium Glutamate (MSG) 🔥 | ¼ tsp | Optional umami booster |
Onion powder is the star here—Diamond Crystal brand gives you that fine, even grind that dissolves perfectly. Bulk bins at Whole Foods or Trader Joe's are your best bet for freshness, but the regular grocery store stuff works fine if it's labeled '100% onion powder' (no fillers). The garlic powder should be freshly ground—pre-ground loses potency fast. For the dairy notes, powdered nonfat milk is a game-changer (it mimics the tangy creaminess of sour cream without moisture). If you can't find it, dry milk powder from the baking aisle works too. Pro tip: Toast the onion and garlic powders in a dry pan for 30 seconds to deepen their flavors—trust me, it makes a difference.
No powdered nonfat milk? Dry milk powder is your next best option, but you'll need about half the amount of the blend. Short on MSG? Extra garlic powder (double the amount) or a pinch of soy sauce powder adds umami. The sugar can be swapped for powdered stevia if you're watching carbs (use half the amount). For the salt, Morton kosher salt works but has finer grains—adjust to taste. The dried parsley flakes? Penzeys brand has the most vibrant color, but any grocery store version will do. Want to make this gluten-free? Check your onion powder label—some brands process in shared facilities.
This blend keeps indefinitely in an airtight container in a cool, dark place. I store mine in a amber glass jar with a tight seal—no light or moisture gets in. For best flavor, shake well before each use (the ingredients settle). Make a double batch—you'll want this on hand for everything from chips to popcorn to roasted potatoes. The MSG is optional but absolutely essential for that authentic Potato Corner punch. If you skip it, add an extra pinch of salt to compensate. Freeze portions if you're not using it often—it won't lose potency, but the parsley might darken slightly (just stir it back up before using).

Step-by-step instructions for potato corner sour cream and onion powder recipe
Transform ordinary mashed potatoes into an extraordinary flavor experience with this bold, restaurant-quality blend.
Combine Dry Ingredients in a Mixing Bowl
In a medium-sized mixing bowl, I like to start by adding the 3 tablespoons of onion powder first. This creates a flavor base that will permeate every spoonful of your mashed potatoes. Using a whisk, gently stir in the 1 tablespoon of garlic powder next—this is where the savory depth begins to build.
Now add the 2 tablespoons of powdered nonfat milk and 1 tablespoon of granulated sugar. The powdered milk will contribute a subtle creaminess without adding moisture, while the sugar balances the sharpness of the onion and garlic. At this stage, you're essentially creating a dry flavor matrix that will transform your mashed potatoes from good to extraordinary.
Incorporate Seasonings for Complex Flavor
Measure out the 1.5 teaspoons of Diamond Crystal kosher salt and add it to the bowl. This is your primary seasoning, so take a moment to distribute it evenly throughout the mixture. Next, add the 0.5 teaspoon of dried parsley flakes and 0.5 teaspoon of ground black pepper. These ingredients might seem small, but they add layers of complexity—bright green notes from the parsley and a subtle heat from the pepper that will elevate your mashed potatoes to new heights.
I always use freshly ground black pepper for this step because pre-ground pepper loses its potency quickly. The parsley flakes should be finely distributed to ensure even flavor in every bite. This is where the magic really starts to happen—the combination of these seasonings creates a flavor profile that's far more sophisticated than standard mashed potatoes.
Add the Umami Booster for Restaurant-Quality Depth
This is the step that takes your blend from good to truly exceptional. Add the 0.25 teaspoon of monosodium glutamate (MSG) to the bowl. I know some people are hesitant about MSG, but trust me—this tiny amount adds a subtle umami depth that makes all the difference in restaurant-quality dishes. It's not about making your potatoes taste "chemical"; it's about enhancing the natural flavors already present in your ingredients.
The MSG works by amplifying the savory notes in your potatoes, making them taste more like they've been simmered for hours rather than minutes. This is particularly important for mashed potatoes, which can sometimes taste bland even when made with high-quality ingredients. The MSG ensures that every bite is packed with flavor without overpowering the natural taste of the potatoes.
Mix Thoroughly for Even Distribution
Using your whisk, blend all the ingredients together until you achieve a completely homogeneous mixture. This step is crucial—you want every tablespoon of your blend to contain exactly the same ratio of flavors. I like to take a small spoon and break up any clumps that might form, ensuring that even the powdered milk is fully incorporated.
At this point, your blend should look like a fine, golden powder with no visible streaks of any single ingredient. The texture should be smooth and consistent, ready to be sprinkled directly onto your mashed potatoes. This thorough mixing ensures that you'll get that perfect flavor boost in every bite, no matter how you serve your potatoes.
Store Properly for Maximum Freshness
Transfer your completed blend to an airtight container. I prefer glass jars with tight-sealing lids for this purpose—they keep the blend fresh and prevent any moisture from affecting the texture. Store it in a cool, dark place like your pantry, where it will maintain its potency for up to 6 months. This makes it perfect for keeping on hand for all your mashed potato needs throughout the year.
The key to long-term storage is keeping the blend completely dry. Any moisture will cause clumping and reduce the effectiveness of the seasonings. When you're ready to use it, simply shake the container well before each application to ensure even distribution of all the flavors. This blend is so versatile that it can also be used to enhance other dishes like soups, casseroles, or even scrambled eggs for an instant flavor boost.
Pro Tips For Making Potato Corner Sour Cream And Onion Powder
- Whisk the dry mix first: Stir onion powder, garlic powder, powdered nonfat milk, and sugar together before adding liquid—this prevents clumping and ensures even distribution. I learned this the hard way when my first batch had gritty pockets of unmixed powder hiding in the corners.
- Salt the potatoes generously: Use 1 teaspoon Diamond Crystal kosher salt per pound of potatoes before cooking—they absorb it better than sprinkling later. (Yes, even if you’re using salted butter or sour cream afterward; trust the process.)
- Don’t skip the sour cream step: Fold in sour cream last, when the potatoes are just off the heat—adding it too early makes them gummy. Warm the sour cream slightly first (30 seconds in the microwave) for creamier texture without curdling.
- Taste before adding extra sugar: The powdered nonfat milk and onion powder already sweeten the mix—add granulated sugar sparingly and taste as you go. I used to dump the full tablespoon and end up with something cloying; now I start with half and adjust.
Flavor customization for this dish
Spicy Kick
If you love heat, add ½ teaspoon cayenne pepper or 1 teaspoon smoked paprika to the base blend. For a smoky twist, I’ve found that ½ teaspoon chipotle powder (like Penzeys brand) adds depth without overwhelming the creamy notes.
Start with half the amount and adjust to taste—this blend is already potent, and you don’t want to lose the signature tang. 🌶️
Herb Variations
Swap out the parsley for dried dill flakes (½ teaspoon) or chives powder (¼ teaspoon) for a brighter, more herbaceous profile. I once replaced it entirely with dried chervil (½ teaspoon), which gave a delicate anise-like note that paired beautifully with roasted potatoes.
For a Mediterranean twist, add ½ teaspoon dried oregano alongside the parsley.
Sweet & Tangy Twist
Increase the sugar to 2 tablespoons and add ½ teaspoon citric acid (found in the baking aisle) for a tangy kick. This mimics the sour cream’s acidity without dairy.
For a caramelized finish, toast the blend in a dry pan for 1 minute over low heat—it develops a nutty sweetness that’s perfect for sweet potato mash. 🍯
Dairy-Free Option
Replace the powdered nonfat milk with 2 tablespoons nutritional yeast for a cheesy, umami-rich alternative. I’ve also used 1 tablespoon coconut milk powder for a subtly tropical note that still complements the onions. The texture becomes slightly grainier, but the flavor holds up beautifully on popcorn or roasted nuts.
Bold & Smoky
For a campfire-inspired version, add ½ teaspoon liquid smoke (like Wright’s brand) mixed into the powdered milk before combining. Alternatively, toast 1 teaspoon coffee grounds with the onion powder before mixing—it adds a deep, earthy complexity that works surprisingly well. This variation is my go-to for game day snacks. 🔥
Mild Family-Friendly
Reduce the onion powder to 2 tablespoons and omit the MSG entirely. Add ½ teaspoon dried basil** instead of parsley for a sweeter, more approachable flavor. This version is perfect for kids’ mashed potatoes or buttery corn on the cob.
I’ve even used it as a seasoning for homemade pretzels with great success.
