The Worst Boxed Au Gratin Potatoes on Grocery Shelves Exposed by Food Critics
Across extensive grocery aisle taste test data gathered throughout late 2025 and 2026, culinary panels systematically blind-tested leading national names and popular grocery private labels. The differences between high-scoring staples and bottom-dwellers boiled down to starch gelatinization and real cheese solids.
| Brand & Variety | Sodium per Serving | Primary Sauce Thickeners | Critic Panel Outcome |
|---|---|---|---|
| Betty Crocker Au Gratin | 620mg | Modified corn starch, maltodextrin | Ranked low; noted for watery sauce consistency and pronounced metallic cheese aroma. |
| Idahoan Homestyle Casserole | 560mg | Real potato starch, dairy whey, cheddar blend | Top-tier finisher; thick sauce cling, tender rehydration, rich real-cheese flavor profile. |
| Kroger / Great Value Store Brands | 680mg, 740mg | Maltodextrin, corn syrup solids, vegetable oil | Inconsistent; high rates of gritty powder sediment and unevenly cooked, rubbery potato slices. |
| Simply Potatoes Homestyle Au Gratin (Refrigerated) | 510mg | Fresh dairy cream, real cheddar, cultured milk | Clear winner overall; fresh cut texture completely bypasses dehydrated cardboard shortcomings. |
