Picnic Season Prep: Only 3 ingredients. I pop this in before running errands so supper is completely handled.

This 3-ingredient oven picnic season prep is my kind of weeknight magic: you toss everything into a metal baking pan, slide it into the oven, and head out to run errands while the house fills with the smell of supper. By the time you’re home, you’ve got a bubbling, amber-edged chicken-and-potato casserole with a crisp, almost charred top and saucy, glistening edges. It’s the kind of simple, practical dish I lean on all spring and summer when we’re bouncing between ball games, work, and planning for weekend picnics.

Spoon the chicken and potatoes onto plates and drizzle those caramelized pan juices over the top. It’s lovely with a simple green salad, sliced cucumbers and cherry tomatoes, or some buttered corn on the cob. For a picnic-style spread at home, add a store-bought coleslaw, a basket of dinner rolls, and some fresh fruit. Leftovers are great tucked into warm pitas or rolls with a little lettuce for an easy next-day picnic sandwich.

Servings: 4

2 pounds boneless, skinless chicken thighs

Preheat your oven to 400°F (200°C). Use the middle rack so the top can brown nicely without burning.

Lightly grease a metal 9x13-inch baking pan or similar metal roasting pan. Metal helps you get that crisp, charred top and bubbling amber edges.

Pat the chicken thighs dry with paper towels and trim any large pieces of fat. This helps them brown better and keeps the sauce from getting too greasy.

Add the halved baby potatoes to the prepared pan in an even layer. Nestle the chicken thighs on top of and around the potatoes so everything fits in a single, mostly snug layer.

Pour the Italian dressing evenly over the chicken and potatoes, turning the pieces with a spoon or tongs so everything is well coated. Spread the chicken back out in a single layer on top so it can brown.

Cover the pan tightly with foil and place it in the preheated oven. Bake covered for 25–30 minutes to let the chicken cook through and the potatoes start to soften.

After 25–30 minutes, carefully remove the foil (watch for steam). Give the potatoes a gentle stir in the pan juices, then rearrange the chicken pieces on top again so the meaty side is facing up.

Return the uncovered pan to the oven and bake for another 25–35 minutes, or until the chicken is deeply browned, the potatoes are tender when pierced with a fork, and the dressing has reduced to a glistening, bubbling sauce with amber, slightly charred edges around the pan.

If you’d like a deeper char on top, switch the oven to broil for 2–4 minutes at the end, watching closely so the edges get caramelized and crisp but do not burn.

Let the casserole rest on the counter for about 5–10 minutes before serving so the bubbling sauce settles a bit and thickens. Spoon the chicken and potatoes onto plates and scrape up all those flavorful amber pan juices to drizzle over each serving.

You can easily adjust this to fit your family. For milder eaters, choose a creamy Italian or ranch-style dressing instead of a zesty or spicy one. If you want more color and veggies, tuck a handful of baby carrots or thick-cut bell pepper strips around the potatoes before baking (this technically adds ingredients, but it won’t hurt the recipe if you’re not strict about the 3-ingredient idea). For a slightly smoky flavor, use a roasted red pepper or balsamic Italian dressing. If you prefer chicken breasts, cut them into large chunks and reduce the total bake time by about 10 minutes, checking for doneness early so they don’t dry out. To make cleanup easier, line the metal pan with heavy-duty foil, but still use metal for that crisp, charred top. Food safety tips: Always wash your hands, cutting board, and any utensils that touch raw chicken with hot, soapy water before using them on cooked food. Make sure the chicken reaches an internal temperature of 165°F (74°C) in the thickest piece before serving; if you don’t have a thermometer, cut into a piece to be sure the juices run clear and there is no pink. Refrigerate leftovers within 2 hours and reheat until steaming hot before eating.
