This oven baked 3-ingredient bouillon potato bake is pure cozy, rainy-day comfort food. My grandfather used to throw this together on gray April evenings when the house felt chilly and everyone was tired from the day. He’d slice up a big pile of potatoes, whisk bouillon into hot water, and let the oven do the rest. The potatoes come out incredibly fork tender with rich, savory flavor and those caramelized brown edges that make you want to scrape the pan clean. It’s the kind of recipe you make when you’re short on time, low on groceries, but still craving something warm and homemade.
Serve this bouillon potato bake straight from the glass baking dish with a big spoon and let everyone help themselves. It’s perfect next to simple roasted chicken, pan-seared pork chops, or grilled sausages. For a lighter meal, pair it with a crisp green salad or steamed green beans. I also love reheating leftovers in a skillet the next morning and topping them with a fried egg for an easy breakfast-for-dinner situation.
Oven Baked 3-Ingredient Bouillon Potato BakeServings: 4
Ingredients
2 1/2 pounds russet or Yukon Gold potatoes, thinly sliced (about 1/8–1/4 inch thick)
3 cups hot water
3 tablespoons bouillon paste or granulated bouillon (chicken or vegetable)
Directions
Preheat your oven to 400°F (200°C). Lightly grease a 9x13-inch glass baking dish so the potatoes don’t stick and those edges can get nicely browned.
In a heatproof bowl or large measuring cup, whisk the bouillon paste or granules into the hot water until completely dissolved. Taste the broth; it should be well-seasoned and savory. If it tastes weak, add up to 1 more teaspoon bouillon, but remember it will concentrate as it bakes.
Scrub the potatoes well and peel them if you prefer. Using a sharp knife or mandoline, slice the potatoes into thin, even rounds about 1/8–1/4 inch thick. The more even the slices, the more evenly they’ll cook and become fork tender.
Layer the sliced potatoes evenly in the prepared glass baking dish. You don’t need to be perfect, but try to spread them out rather than stacking them in a deep pile so the broth can reach all the slices and the top can brown.
Slowly pour the hot bouillon mixture over the potatoes, tilting the dish slightly if needed so the liquid distributes throughout. The potatoes should be mostly submerged, with just a few edges peeking out on top.
Cover the baking dish tightly with foil. Bake on the middle rack for 40–45 minutes, until the potatoes are very tender when pierced with a fork. This covered time is what makes them soft and creamy all the way through.
Carefully remove the foil (watch for steam), then return the dish to the oven uncovered. Bake for another 20–25 minutes, until most of the liquid has reduced, the potatoes are deeply fork tender, and the top has rich brown, roasted edges.
If you want extra color on top, you can move the dish to the upper rack for the last 5 minutes of baking, keeping a close eye so the edges don’t burn. Let the potatoes rest for 5–10 minutes before serving so the hot broth settles slightly and the flavors come together.
Serve hot, scooping down to the bottom of the dish to get the tender slices and the concentrated savory broth in each portion.
Variations & Tips
Use any bouillon you like: chicken for a classic cozy flavor, vegetable to keep it vegetarian, or beef for a deeper, almost French-onion-soup vibe. If you only have bouillon cubes, just dissolve 3–4 standard cubes in the 3 cups hot water (check the package for strength and adjust to taste). For a slightly richer version without adding ingredients, slice the potatoes a bit thicker and bake a touch longer; they’ll hold their shape more and soak up the broth differently, giving you a creamier center with extra browned edges. You can also adjust texture by baking a little longer uncovered if you prefer less broth and more concentrated, almost roasted potatoes. For meal prep, slice the potatoes in the morning and keep them submerged in cold water in the fridge, then drain and assemble right before baking. Leftovers reheat well in the oven or a skillet, and if you crisp them in a pan, they make an easy base for leftover roast meat or a quick egg on top.
