Stew meat and mushrooms simmers away in a slow cooker all day, and is then finished off with a little cornstarch for thickening. Served atop egg noodles or mashed potatoes, this Slow Cooker Beef Tips is a great dinner for busy weekdays.
Whisk together cream of mushroom soup, water, onion soup mix, and black pepper in the bowl of a slow cooker. Add beef and mushrooms, stirring gently to coat.
Cover and cook on low for 8-10 hours.
Just before serving (eg. when preparing egg noodles or anything else you'll be serving),with the slow cooker still on low (return to low if it kicked over to warm), whisk in corn starch. Cook on low for 5 minutes, whisking frequently.
Serve over egg noodles, mashed potatoes, or rice.
