This 5-ingredient slow cooker summer roast is my go-to when I want a cozy, Sunday-style dinner without hovering over a hot stove all afternoon. It starts with a raw beef tri-tip roast and a few pantry staples, then the slow cooker does all the work while you’re out at the pool, ball games, or just catching up on life. The end result is a pull-apart, ultra-juicy, gelatinous roast in a dark, savory gravy that tastes like you fussed for hours—without actually being stuck in the kitchen.
I like to serve this roast over creamy mashed potatoes or buttered egg noodles so they can soak up all that glossy, umami-rich gravy. In the summer, I’ll add easy sides like a crisp green salad, grilled corn on the cob, or sliced tomatoes with a little salt and olive oil. Leftovers are great piled onto toasted buns with a scoop of coleslaw or tucked into tortillas with pickled onions for an easy weeknight remix.
5-Ingredient Slow Cooker Summer Tri-Tip RoastServings: 6
Ingredients
3 to 3.5 lb raw beef tri-tip roast, trimmed of excess surface fat
1 (1 oz) packet dry onion soup mix
1 cup low-sodium beef broth
1/2 cup Worcestershire sauce
2 tbsp olive oil (or any neutral cooking oil)
Directions
Pat the raw beef tri-tip roast dry with paper towels. This helps it brown better and keeps the gravy from getting greasy.
In a large skillet over medium-high heat, heat the olive oil until shimmering. Sear the tri-tip on all sides, about 2–3 minutes per side, until a deep brown crust forms. (If you’re really pressed for time, you can skip searing, but it adds nice flavor and color to the final gravy.)
Place the seared tri-tip roast into the slow cooker, fat side up so it self-bastes as it cooks.
In a small bowl or measuring cup, whisk together the dry onion soup mix, beef broth, and Worcestershire sauce until mostly dissolved. Pour this mixture evenly over the roast in the slow cooker.
Cover and cook on LOW for 7–9 hours, or on HIGH for 4–5 hours, until the tri-tip is very tender and easily pulls apart with two forks. It should be surrounded by a dark, glossy, umami-rich gravy.
Once cooked, use two forks to gently pull the roast apart into large, fibrous chunks right in the slow cooker, mixing it with the gelatinous gravy. Taste and adjust seasoning with a little salt and pepper if needed.
Turn the slow cooker to WARM and let the shredded roast sit in the gravy for 10–15 minutes before serving so it can soak up even more flavor. Serve straight from the slow cooker with plenty of the dark, glistening gravy spooned over each portion.
Variations & Tips
To keep this at 5 ingredients, I lean on pantry staples, but you can customize it a bit while still keeping the spirit of the recipe. For a slightly sweeter, BBQ-style twist, replace half the Worcestershire sauce with your favorite barbecue sauce and add a little smoked paprika when you sear the meat. If you like a peppery kick, sprinkle freshly ground black pepper over the tri-tip before searing and stir a pinch of red pepper flakes into the broth mixture. For extra richness, you can stir in 1–2 tablespoons of cold butter at the end until melted into the hot gravy. If you want a thicker gravy, transfer 1/2 cup of the hot cooking liquid to a bowl, whisk in 1 tablespoon cornstarch, then stir that slurry back into the slow cooker and cook on HIGH for 10–15 minutes until glossy and slightly thickened.
Food safety tips: Always start with a fully thawed beef tri-tip roast; cooking from frozen in a slow cooker can keep the meat in the temperature “danger zone” too long. Keep raw meat and its juices away from ready-to-eat foods, and wash your hands, cutting boards, and knives with hot, soapy water after handling the raw roast. Make sure your slow cooker is at least half full but not more than about two-thirds full so it heats properly. Use a food thermometer if you’re unsure; the roast should reach at least 145°F internally, though for shredding tenderness it will typically be higher. Refrigerate leftovers within 2 hours of cooking in shallow containers, and use within 3–4 days, or freeze for longer storage.
