Every Sunday after church, my mother would set a big oval platter of these potato croquettes in the center of the table, still sizzling and golden from the oven. Dad would always sneak one before grace, swearing they tasted just like clouds wrapped in a crisp coat. This is the pared-down, three-ingredient version I still make today when the house is quiet but I want to feel everyone close again. The recipe is pure Midwestern practicality: leftover mashed potatoes, an egg, and breadcrumbs, turned into something special enough that my grown kids and their families still ask for them whenever they come home.
Serve these oven-baked potato croquettes right on the platter you baked them on or transfer to a vintage ceramic dish if you have one, so they stay hot and homey. They’re wonderful alongside roast chicken, meatloaf, or a simple ham steak, with a green vegetable like peas, green beans, or a tossed salad to balance the richness. A little bowl of ketchup, brown gravy, or sour cream on the side lets everyone dip as they like. They also make a fine snack on their own with a cup of coffee or iced tea while you sit and visit at the kitchen table.
Oven-Baked 3-Ingredient Potato CroquettesServings: 12 croquettes (about 4–6 servings)
Ingredients
3 cups cold mashed potatoes (plain, well-seasoned from a previous meal)
1 large egg, lightly beaten
1 1/2 cups plain dry breadcrumbs (divided, plus a little extra if needed)
Directions
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it so the croquettes don’t stick.
In a medium mixing bowl, stir the cold mashed potatoes to loosen them up a bit. If they are very stiff from the refrigerator, let them sit on the counter 10–15 minutes so they are easier to work with.
Sprinkle 1/2 cup of the dry breadcrumbs over the mashed potatoes and mix gently with a spoon or your clean hands until the crumbs disappear into the potatoes. This helps the croquettes hold their shape without needing extra ingredients.
Add the beaten egg to the potato mixture and mix until everything is evenly combined. The mixture should be soft but able to hold together when you squeeze a small amount in your hand. If it feels too loose or sticky to shape, sprinkle in more breadcrumbs a tablespoon at a time, just until it holds.
Pour the remaining 1 cup of dry breadcrumbs into a shallow dish or pie plate and spread them out in an even layer for coating.
Scoop up about 2 tablespoons of the potato mixture and roll it gently between your palms into an oval or fat cylinder, about the size of a large thumb or small egg. Set it on a plate and repeat with the remaining mixture, making 10–14 croquettes depending on size.
Roll each shaped croquette in the dish of dry breadcrumbs, pressing lightly so the crumbs cling and form a good, even coat. Place the breaded croquettes on the prepared baking sheet, leaving a little space between each one so the heat can circulate and crisp them all around.
Lightly mist or brush the tops and sides of the croquettes with a bit of neutral oil if you like a deeper golden color, though they will still crisp without it thanks to the dry heat of the oven.
Bake on the middle rack for 15 minutes, then carefully turn each croquette with a spatula or tongs so they brown evenly. Return to the oven and bake another 10–15 minutes, or until the croquettes are a deep golden brown and crisp on the outside.
Remove the baking sheet from the oven and let the croquettes rest for 5 minutes. This brief rest helps the centers stay fluffy and keeps them from falling apart when you move them.
Transfer the croquettes to a warm vintage platter or serving dish. Serve hot, while the outsides are crisp and the insides are still fluffy and steamy, just the way my dad liked them on those slow Sunday afternoons.
Variations & Tips
If your mashed potatoes are very plain, you can season them before shaping with a little salt and pepper without breaking the 3-ingredient spirit, since most mashed potatoes already have some seasoning. For a slightly richer croquette, you can use mashed potatoes that were made with butter and milk; they will bake up creamier inside. If your leftover potatoes are very loose and milky, be prepared to add an extra spoonful or two of breadcrumbs until the mixture firms up enough to shape. For a crisper shell, toast the dry breadcrumbs in a dry skillet over medium heat for a few minutes before coating, stirring often so they don’t burn. These croquettes can be formed ahead, arranged on a baking sheet, and refrigerated for up to 8 hours before baking; just cover lightly with plastic wrap so they don’t dry out. For reheating leftovers, place them on a baking sheet and warm in a 350°F (175°C) oven for about 10 minutes so they regain their crispness instead of turning soggy in the microwave. Food safety tips: Always use cold, properly stored mashed potatoes that have been refrigerated within 2 hours of cooking and kept below 40°F (4°C). Do not use mashed potatoes that have sat out at room temperature for a long church potluck or family gathering. Once the egg is mixed into the potatoes, keep the mixture chilled if you are not shaping and baking right away, and bake the croquettes until they are piping hot in the center. Refrigerate any leftovers within 2 hours of serving and eat them within 3–4 days.
