You're thickening soup and the recipe calls for potato flakes, but the box is empty. Potato flakes absorb liquid quickly while adding body and a mild starchy flavor to everything from bread dough to casseroles.

They work as a thickener, moisture holder, and binder all at once. Most kitchens have at least one substitute that covers these functions without needing a trip to the store.
Instant mashed potatoes replace potato flakes 1:1 in baking and soups-they're nearly identical in function. Potato starch works for thickening at ⅔ the amount but skips the moisture. Potato flour matches volume in baked goods and adds more moisture than flakes.
7 Alternatives to Replace Potato Flakes
Potato flakes do triple duty-they thicken, bind, and hold moisture. The swaps below match these functions in different combinations depending on your recipe.

| # | Substitute | Best For | Ratio | Key Note |
|---|---|---|---|---|
| 1 | Instant Mashed Potatoes | ✨ Both | 1:1 | Slightly more salt |
| 2 | Potato Starch | 🍳 Cooking | ⅔ amount | No moisture added |
| 3 | Potato Flour | 🥧 Baking | 1:1 | Denser texture results |
| 4 | Bread Crumbs | 🍳 Cooking | 1:1 | Binds only-no thickening |
| 5 | Tapioca Starch | 🍳 Cooking | ¾ amount | Gels fast on heat |
| 6 | Cauliflower Mash | 🌱 Vegan | 1:1 fresh | Different flavor |
| 7 | DIY Blend | ✨ Both | 2:1 mix | Needs manual blending |
1. Instant Mashed Potatoes 🥔
Instant mashed potatoes are dehydrated potatoes with added seasonings-potato flakes with salt and sometimes milk powder. They thicken soups, bind meatloaf, and add moisture to bread dough just like flakes do.
Use them 1:1 by volume. They absorb liquid at the same rate as potato flakes.
- ✅ Nearly identical function-thickens and binds
- ✅ Widely available in most pantries
- ⚠️ Contains added salt-reduce other salt in recipe
- ⚠️ May include dairy if recipe needs vegan option
The extra seasoning usually doesn't disrupt savory dishes. In baking, the salt rarely causes problems unless you're making something sweet.
2. Potato Starch 🥄
Potato starch is pure starch extracted from potatoes-no fiber, no moisture-holding structure. It thickens sauces and soups with concentrated power but won't add the body potato flakes bring to baked goods.
Use ⅔ the amount of potato flakes called for. The concentrated starch means less volume does the same thickening work.
- ✅ Gluten-free thickener for soups and gravies
- ⚠️ Doesn't absorb or hold moisture like flakes
It works in recipes where you're just thickening liquid-chowders, stews, or pie fillings. Skip it in bread or muffins that rely on flakes for moisture and structure.
3. Potato Flour 🍞
Potato flour is ground whole potato-it includes the starch plus the fiber and cell structure that hold moisture. It makes baked goods tender and extends freshness by trapping water in bread and rolls.
Use equal volume to potato flakes. The moisture-holding function matches closely, though the texture runs denser.
- ✅ Excellent for yeast breads and soft rolls
- ✅ Extends shelf life of baked goods
- ⚠️ Creates denser crumb than flakes
4. Bread Crumbs 🍽️
Bread crumbs absorb moisture and bind ingredients in meatloaf, meatballs, and coatings. They don't thicken liquids-they just soak up wetness and help everything stick together.
Use equal volume to potato flakes in binding applications. They work great in meat mixtures and breading.
Bread crumbs can't replace the thickening function in soups or sauces. They also add gluten, so they're not suitable for gluten-free recipes that originally used potato flakes.
5. Tapioca Starch 🌾
Tapioca starch thickens liquids without adding flavor-it turns clear when cooked and creates a slightly glossy texture. It doesn't hold moisture the way potato flakes do, so it only works for thickening.
Use 75% of the volume of potato flakes. Tapioca gels fast once it hits heat, so add it near the end of cooking.
It shines in fruit fillings and sauces where you want a clear finish. Skip it in baking-it won't add the moisture or structure potato flakes bring to bread dough or cake batter.
6. Cauliflower Mash 🥦
Cauliflower mash-either fresh or dehydrated-brings moisture and binding power to low-carb baking and casseroles. The flavor runs slightly sweet and earthy instead of neutral starchy.
Use 1:1 for fresh cauliflower or 1:1.5 for dehydrated (it needs more to match the volume). It works in recipes where potato flavor isn't critical.
- ✅ Low-carb option for keto baking
- ⚠️ Different flavor-won't taste like potato
7. DIY Potato Flake Blend 🔧
Mixing instant mashed potatoes with potato starch rebuilds potato flakes at home. The instant potatoes supply moisture-holding structure while the starch concentrates thickening power.
Use 2 parts instant mashed potatoes to 1 part potato starch. Mix dry before adding to your recipe.
This blend works when you have both ingredients on hand but no flakes. It covers all three functions-thickening, moisture, and binding-without needing a store run.
The texture varies slightly depending on the brand of instant potatoes you use. Some run finer, others chunkier-but the function stays consistent.
Picking Your Potato Flake Swap
- For baking: Instant mashed potatoes or potato flour work 1:1
- For thickening soups: Potato starch at ⅔ amount concentrates power
- For binding meat: Bread crumbs match volume and absorb moisture
Frequently Asked Questions
Yes, use instant mashed potatoes 1:1 in bread recipes. They absorb liquid and add moisture the same way potato flakes do. Watch the salt level-instant potatoes usually contain more seasoning than plain flakes.
Potato flour is ground whole potato with fiber and moisture-holding structure-it works in baking. Potato starch is pure extracted starch-it thickens liquids but doesn't add moisture. They're not interchangeable in most recipes.
Regular flour thickens liquids but doesn't absorb moisture or bind like potato flakes. It works in a pinch for thickening soups-use half the amount. It won't replicate the texture potato flakes create in baking or binding applications.
Potato flakes are plain dehydrated potatoes. Instant potatoes are potato flakes with added seasonings like salt, milk powder, or butter flavoring. They work the same in recipes-just adjust salt to account for the seasoning in instant potatoes.
You can dehydrate mashed potatoes and grind them into flakes using a food dehydrator or low oven. Spread thin layers on parchment and dry at 125°F for 6-8 hours, then pulse in a food processor. The texture won't match commercial flakes exactly but works in most recipes.

7 Best Substitutes for Potato Flakes
Ingredients
Method
- Choose the substitute based on your recipe needs: thickening, baking, or binding.
- If needed, prepare the substitute by blending or mixing to create uniform texture (e.g., DIY Blend).
- Measure and apply the substitute using the indicated ratio for the potato flakes amount.
- Adjust seasoning as necessary, especially when using substitutes with added salt like instant mashed potatoes.
- Check consistency and texture after mixing or warming; adjust liquid or substitute amount if needed.
Notes
- Instant mashed potatoes offer the closest 1:1 replacement but may add salt and dairy.
- Potato starch and tapioca starch are great for thickening but do not add moisture.
- Bread crumbs bind but do not thicken; not suitable for gluten-free recipes.
