This old-fashioned 3-ingredient oven bake is the kind of supper that feels like it came straight from a church cookbook or a Sunday family table in the 1960s, when simple pantry ingredients and a slow oven did most of the work. It is especially handy on a busy August day because you can get everything tucked into the casserole dish hours ahead, then let it roast into a tender, fibrous, caramelized main dish with a rich dark glaze by dinnertime.
Serve this bake with mashed potatoes, buttered egg noodles, or fluffy rice to catch every bit of the sweet-savory sauce. A simple green bean side, corn on the cob, or a crisp lettuce salad balances the richness nicely, and warm rolls are always welcome for scooping up the extra glaze from the plate.
3-Ingredient Oven 1960s Sunday Best Bake
Serves 6
Ingredients
3 to 4 pounds bone-in pork shoulder roast
1 cup dark amber bottled barbecue sauce
1 packet dry onion soup mix
Directions
1. Preheat the oven to 325°F. Place the pork shoulder roast in a 9x13-inch Pyrex glass casserole dish.
2. In a small bowl, stir together the barbecue sauce and dry onion soup mix until fully combined, then spread the mixture all over the roast.
3. Cover the dish tightly with foil and bake for 3 1/2 to 4 hours, until the pork is very tender and easy to pull apart with a fork.
4. Uncover the roast and bake 20 to 30 minutes more, basting once or twice, until the glaze is dark, sticky, and caramelized around the edges.
5. Let the roast rest for 10 to 15 minutes, then pull or slice and serve with the pan glaze spooned over the top.
Variations & Tips
Chicken Version: If your family prefers chicken, use 6 bone-in, skin-on chicken thighs and reduce the covered baking time to about 1 hour, then uncover and bake until the glaze is sticky and the chicken is cooked through.
For Picky Eaters: Choose a sweeter, milder barbecue sauce if anyone at your table is sensitive to smoky or spicy flavors. This helps the finished bake taste familiar and kid-friendly.
Make-Ahead Tip: You can assemble the roast with the sauce mixture in the casserole dish in the morning, cover it, and refrigerate it until you are ready to bake. Let it sit at room temperature for about 20 minutes before putting it in the oven.
Extra Sauce Tip: If you like plenty of sauce for potatoes or noodles, add an extra 1/2 cup barbecue sauce before baking. The roast will stay just as tender and give you more glaze for serving.
Texture Tip: For the most old-fashioned Sunday supper feel, cook until the meat is fork-tender enough to pull into thick, saucy pieces rather than neat slices. That gives you more caramelized bits and more surface for the glaze.
