This is my bare-minimum, busy-day comfort bake inspired by old depression-era cooking: one big starchy block, a little fat, a splash of broth, and time. I call it my 5-ingredient oven depression era charred bake using a starchy block, and it’s exactly what I reach for on those rainy, gray evenings when I want dinner handled hours ahead with almost zero effort. You tuck a block of potatoes into a cast iron pan, pour over a simple onion-garlic broth, dot with butter, and just let the oven do its thing until the edges are deeply caramelized and the top is glistening and steamy. It’s cozy, cheap, filling, and feels like something a great-grandma would’ve made—only with the convenience of modern meal prep.
Serve this starchy block straight from the cast iron pan with a big green salad or steamed broccoli to balance the richness. It’s amazing next to simple baked chicken thighs, roasted sausages, or a pan-seared pork chop, but it can also be the star with just a fried or soft-boiled egg on top. I like to spoon any extra oniony broth from the pan over the slices, then add a quick crunchy side like pickles or a slaw to cut through the buttery, caramelized edges.
5-Ingredient Oven Depression Era Charred Starchy Block BakeServings: 4
Ingredients
2 pounds frozen hash brown potato patties, kept in a solid block if possible
2 tablespoons unsalted butter, cut into small pieces
1 cup low-sodium chicken or vegetable broth
1 medium yellow onion, thinly sliced
1 teaspoon kosher salt (plus more to taste)
Directions
Preheat your oven to 325°F (165°C). Place a 10–12 inch deep cast iron skillet or heavy oven-safe pan on the counter; no need to preheat the pan.
Arrange the frozen hash brown potato patties tightly together in the cast iron skillet so they form one solid starchy block. If they’re slightly separated, press them together with your hands so they sit snugly and fill most of the pan.
Scatter the thinly sliced onion evenly over and around the potato block, tucking some slices down the sides so they can melt into the broth and edges as they cook.
Sprinkle the kosher salt evenly over the potatoes and onions. Dot the top of the block with the small pieces of butter, spacing them out so they melt and baste the surface.
Pour the chicken or vegetable broth into the skillet, aiming for the sides of the pan so you don’t wash the salt off the top. The liquid should come up the sides of the block by about 1/4–1/3 inch; it will reduce and help create those charred, caramelized edges.
Cover the skillet tightly with foil. Bake at 325°F for 1 1/2 hours, undisturbed. This slow, covered time lets the potatoes soften, the onions melt, and the broth soak into the block.
After 1 1/2 hours, carefully remove the foil (watch for steam). Increase the oven temperature to 425°F (220°C). Return the uncovered skillet to the oven and bake for 35–45 minutes, until the top is deeply golden, the edges are charred and caramelized, and the liquid is mostly absorbed or reduced to a syrupy glaze.
If you want even more char on the edges, switch the oven to broil for 2–4 minutes at the end, watching closely so it doesn’t burn. You’re looking for dark, crisp corners and a glistening, steamy top.
Remove the skillet from the oven and let the starchy block rest for 10 minutes so it firms up slightly and slices cleanly. Use a sharp knife or spatula to cut into squares or wedges, scooping up the soft onions and any remaining broth from the bottom of the pan to spoon over each serving. Taste and add a pinch more salt at the table if needed.
Variations & Tips
For a slightly richer version, swap half of the broth for whole milk or light cream (still keeping the total liquid at about 1 cup); this will give you a creamier interior under the charred top. If you want to keep it vegetarian, use vegetable broth and add a tiny extra pinch of salt to make up for the missing savory note from chicken broth. You can also change the vibe with different onions: red onions will give a sweeter, more colorful finish, while leeks (cleaned and sliced) will make it milder and more delicate. If you only have loose frozen hash browns instead of patties, press the shredded potatoes firmly into the skillet to form a tight, even block before adding the onions and broth. For more texture, you can lay an extra potato patty or a thin layer of shreds just on top to create an ultra-crisp lid. To make this more of a full meal, add cooked sliced sausage or leftover shredded chicken tucked down the sides before baking; just keep the total additions modest so the potatoes still form a solid block. This recipe also reheats well: cool, chill in the skillet or a container, then rewarm slices in a hot oven or skillet until the edges crisp back up.
