End of May Bake: Exactly 4 ingredients. I make it when I want dinner handled hours ahead of the neighborhood block party.

This End of May Bake is the kind of four-ingredient supper I lean on when the neighborhood block party is buzzing and I want dinner handled hours ahead. It reminds me of the easy hot dishes my mother would slide into the oven on those first warm evenings when the lilacs were blooming and nobody wanted to fuss over the stove. Everything goes into one square glass baking dish, bakes up with a glistening, savory, bubbly middle and a crispy golden-brown crust on top, and then just waits patiently until you’re ready to eat. It’s simple Midwestern comfort—no fancy tricks, just a hearty make-ahead bake you can count on.

I like to serve this warm with a simple green salad dressed in vinegar and oil, and maybe some sliced garden tomatoes if they’re ready yet. A dish of cottage cheese or coleslaw fits right in with that church-basement feel. If you’re feeding a crowd at the block party, set the baking dish out on a trivet with a big spoon, and offer bowls of pickles, sliced green onions, or a little hot sauce on the side so folks can dress up their own serving. A pan of cornbread or a basket of dinner rolls will help soak up those savory juices.

Servings: 6

2 pounds boneless, skinless chicken thighs, trimmed

Heat your oven to 375°F (190°C). Lightly grease a square 8x8-inch glass baking dish so nothing sticks and you get that nice, clean edge on the crust.

Pat the chicken thighs dry with paper towels and trim any large pieces of fat. Lay them in an even layer in the bottom of the glass baking dish. They can be snug, but try not to overlap too much so they cook evenly and stay juicy.

In a medium bowl, stir together the condensed cream of mushroom soup and sour cream until smooth and well combined. This mixture will look thick—that’s exactly what you want so it bakes up creamy and steamy underneath the crust.

Spread the soup and sour cream mixture evenly over the chicken, making sure all the pieces are covered. This keeps the chicken moist while it bakes and creates that savory sauce that bubbles up around the edges.

Scatter the thawed shredded hash brown potatoes evenly over the top, all the way to the corners. Gently pat them down so they form a fairly even layer; this will crisp into a golden-brown crust as it bakes.

Place the dish on the middle rack of the preheated oven and bake, uncovered, for 50 to 60 minutes, or until the top is deeply golden-brown and crispy, the edges are bubbling, and the chicken reaches an internal temperature of at least 165°F (74°C) in the thickest pieces.

If the top is not as brown and crispy as you’d like after the chicken is done, you can move the dish under the broiler for 2 to 3 minutes, watching closely, until the hash browns are a deeper golden-brown and lightly crisped. Don’t walk away during this step.

Once baked, let the dish rest on the counter for 10 to 15 minutes before serving. This short rest helps the sauce settle, keeps the interior steamy, and makes it easier to scoop neat portions while the crust stays intact and crisp.

If you want dinner handled hours ahead of time, bake the dish earlier in the day, let it cool slightly, then cover and refrigerate. About 30 to 40 minutes before serving, reheat in a 325°F (165°C) oven, uncovered, until hot in the center and the top has crisped back up, then bring it right to the table in the glass dish.

You can swap the cream of mushroom soup for cream of chicken or cream of celery if that’s what you keep in your pantry; it will change the flavor slightly but keep the same comforting character. Boneless, skinless chicken breasts can be used instead of thighs, but check for doneness a little earlier so they don’t dry out. If you like a bit more texture, use the cubed frozen hash browns instead of shredded, or stir a handful of thawed hash browns into the soup mixture and keep the rest on top for an even heartier feel. For a touch of color, you can choose hash browns that already include peppers and onions—this still keeps your ingredient count at four while adding a little extra flavor. To stretch the dish for a crowd, serve it over buttered egg noodles or rice. Food safety tips: Always thaw the frozen hash browns in the refrigerator or in the microwave, never on the counter, to keep them out of the temperature danger zone. Keep raw chicken refrigerated until you’re ready to assemble the bake, and wash your hands, cutting board, and any utensils that touch the raw chicken with hot, soapy water before using them for anything else. Make sure the chicken reaches at least 165°F (74°C) in the thickest pieces before serving. If you bake the dish ahead and cool it, refrigerate within 2 hours and reheat thoroughly until steaming hot all the way through before serving. Leftovers should be cooled quickly, covered, and stored in the refrigerator, and enjoyed within 3 to 4 days.
