This Slow Cooker Catalina Roast Beef is one of those set it and forget it dinners that makes the whole house smell like comfort. Tender chuck roast slow cooks with hearty vegetables in a sweet and savory Catalina sauce that feels like something Grandma would have made, but with a fun little twist.
Step 1: Build the vegetable base - Add the diced celery, chopped carrots, sliced onion, and halved baby potatoes to the bottom of your slow cooker. Spread them out evenly so they cook at the same pace.
Step 2: Add the roast - Place the chuck roast directly on top of the vegetables. No need to brown it first unless you want to, this recipe works beautifully without that extra step.
Step 3: Mix the sauce - In a small bowl, whisk together the Catalina dressing and the dry onion soup mix until fully combined. This is where all that bold flavor starts.
Step 4: Pour it on - Pour the dressing mixture evenly over the roast, making sure some of it runs down over the vegetables too.
Step 5: Slow cook - Cover the slow cooker and cook on low for eight hours or on high for six hours. Low and steady gives you the most tender beef.
Step 6: Serve - Once done, the roast should be fork tender. You can slice it or shred it, then spoon the vegetables and sauce over the top. Serve hot and enjoy.
Notes
Substitutions
Chuck roast: Round roast or rump roast can work, though they may be slightly less tender.
Catalina dressing: French dressing or Russian dressing are great alternatives with a similar flavor profile.
Onion soup mix: A homemade mix of dried onion flakes, beef bouillon, and garlic powder works well.
Vegetables: Parsnips, mushrooms, or sweet potatoes can be swapped in or added.
Potatoes: Yukon gold or red potatoes hold up nicely in the slow cooker.
