What You’ll Need

Here is what you’ll need for this slow cooker steak bites recipe. Find the full measurements in the recipe card below.

Sirloin roast – Lean but tender when cooked low and slow. High in protein and iron. Swap: Chuck roast for richer flavor, bottom round for budget-friendly option.
Olive oil – For searing.
Kosher salt & black pepper – Simple seasoning that enhances the beef.
Aromatics: Onion (finely minced) which melts into the sauce for subtle sweetness, and garlic adds warmth and depth.
Au jus gravy mix – Creates that savory, beef-forward sauce. You can find it in most supermarkets in the dehydrated sauces section.
Beef broth – Helps deglaze and adds moisture.
A splash of Worcestershire or red wine for extra depth – these are optional but I always add them if I have some.
Butter – Adds richness at the end, again this is optional and you can skip it if watching calories.
Fresh parsley – For brightness.

Best Cuts for Slow Cooker Steak Bites

Sirloin roast – Leaner, balanced flavor
Chuck roast – More marbling, ultra tender
Bottom round roast – Economical, needs full cook time
Top sirloin steak – Works if cut thick

Avoid very lean cuts like eye of round unless cooking low for full duration.

Pat beef cubes dry and season with salt and pepper.
Sear in hot oil until well browned (work in batches).

Make-ahead: Cook fully, cool, refrigerate up to 3 days.
Freezer-friendly: Freeze up to 3 months.
Meal prep tip: Portion into containers with rice or potatoes for high-protein lunches.
