Solstice Supper: Just 3 ingredients. This is my absolute favorite trick for busy summer days when I want a hearty dinner but refuse to turn on the oven!

This 3-ingredient slow cooker sunshine casserole is my nod to the hearty, no-fuss dishes that showed up at every Midwestern potluck in the 1980s—usually in a floral Pyrex and always scraped clean by the end of the night. It leans on a fibrous, pull-apart cut of beef, a pantry-staple sauce, and a bright, tangy canned fruit to give you that sweet-savory, mahogany-glazed comfort without ever turning on the oven. On busy summer days when the sun is high and the last thing I want is extra heat in the kitchen, I set this up in the morning, walk away, and come back to a bubbling slow cooker full of tender, shreddable meat and sticky, sunshine-colored sauce.

Serve the meat and its glossy sauce spooned over hot white rice, buttered egg noodles, or a bed of mashed potatoes to soak up every bit of the glaze. A crisp green salad with a sharp vinaigrette or simple cucumber-tomato salad helps cut through the richness. For a more 1980s-inspired spread, add buttered corn, canned green beans warmed with a pat of butter, or a basket of soft dinner rolls to swipe through the slow cooker juices. Leftovers make excellent sandwich fillings on toasted buns with a handful of coleslaw for crunch.

Servings: 6

3 to 3 1/2 pounds boneless beef chuck roast (or similar fibrous, pull-apart cut)

Trim any large, hard pieces of surface fat from the beef chuck roast, but leave some marbling for flavor and tenderness. Pat the meat dry with paper towels so the sauce clings well.

Place the beef chuck roast into the bottom of a 5- to 7-quart slow cooker, positioning it so it lies as flat as possible for even cooking.

In a medium bowl, stir together the barbecue sauce and the entire can of pineapple chunks with their juice until the mixture looks glossy and evenly combined. This creates the sweet-tangy base that will cook down into a mahogany glaze.

Pour the barbecue-pineapple mixture evenly over the beef in the slow cooker, lifting the meat slightly with a spoon or tongs so some of the sauce seeps underneath. The roast should be mostly coated, with sauce pooling around the sides.

Cover the slow cooker with the lid. Cook on LOW for 8 to 10 hours, or on HIGH for 4 to 5 hours, until the beef is fork-tender and easily pulls apart into long, fibrous strands. Avoid lifting the lid frequently, as this releases heat and extends cooking time.

Once the beef is very tender, use two forks to gently pull it apart directly in the slow cooker, shredding it into bite-size pieces. Stir the shredded meat thoroughly into the bubbling sauce and pineapple chunks so everything is well coated and glossy.

If the sauce seems thin after shredding, turn the slow cooker to HIGH, leave the lid slightly ajar, and cook for another 20 to 30 minutes, stirring occasionally, until the liquid reduces to a thick, mahogany glaze that clings to the meat.

Taste the finished casserole and adjust the seasoning if desired by adding a pinch of salt or a splash of additional barbecue sauce. Serve the pull-apart meat hot, spooned out of the slow cooker with plenty of sauce and pineapple in each portion.

To lean even harder into the 1980s potluck vibe, you can swap the barbecue sauce for an equal amount of bottled French or Catalina salad dressing for a brighter, more tomato-forward glaze. If you prefer pork, use a 3- to 4-pound pork shoulder (Boston butt) instead of beef; keep the same cooking times and shred when tender. For a slightly less sweet version, choose pineapple tidbits packed in juice with a lower-sugar barbecue sauce, or drain off half of the pineapple juice before mixing. If you like a bit of heat with your sunshine, stir in a teaspoon or two of crushed red pepper flakes or a spoonful of hot sauce with the barbecue sauce and pineapple. You can also finish the dish with a handful of chopped fresh cilantro or scallions right before serving for a fresh, modern contrast to the retro flavors. For food safety, always start with fully thawed meat; do not put frozen roasts directly into the slow cooker, as they can spend too long in the temperature “danger zone.” Cook on LOW or HIGH only as directed, and use a meat thermometer if you’re unsure—the internal temperature of the roast should reach at least 190°F for easy shredding and safe consumption. Once cooked, hold the casserole on the slow cooker’s WARM setting for up to 2 hours, then cool leftovers quickly and refrigerate within 2 hours of cooking. Reheat leftovers to at least 165°F before serving.
