Ingredients Overview

Each component of this dish has a clear purpose, from building flavor to ensuring the beef is fall-apart tender:

Stew Beef or Chuck Roast (Cubed)

The star of the show. Beef chuck roast or pre-cut stew meat is ideal here because it’s rich in connective tissue and fat, which breaks down beautifully in the slow cooker. This results in incredibly tender, juicy beef bites after hours of gentle simmering.

Butter

The base of the garlic butter sauce. Butter adds richness, silkiness, and depth of flavor. Use unsalted butter so you can control the salt content.

Garlic

Lots of fresh garlic cloves—minced or crushed—are key. Garlic infuses the butter and beef with aromatic intensity as it cooks slowly for hours.

Beef Broth

A small amount of beef broth prevents dryness, adds umami, and helps create a silky sauce. Choose low-sodium broth so the flavors don’t become overpowering.

Worcestershire Sauce

Just a dash enhances the meaty, umami profile of the beef and adds subtle tang and complexity.

Italian Seasoning

A blend of oregano, thyme, rosemary, and basil gives the beef a well-rounded herby aroma. You can also use fresh herbs if preferred.

Salt & Pepper

Simple but essential. Season generously to bring out the full richness of the dish.

Optional Add-ins:

• Red chili flakes – For a little heat.

• Fresh herbs like parsley or thyme – For garnish.

• Mushrooms or pearl onions – Cook alongside the beef for added depth and texture.

Protein Variations

FAQ

1. Can I cook these beef bites on the stovetop?

Yes. Sear the beef, then simmer on low in a Dutch oven with all the ingredients for 2–3 hours until tender.

2. What cut of beef is best?

Chuck roast or stew beef is ideal for slow cooking. It breaks down beautifully and becomes tender over time.

3. Can I add vegetables?

Yes! Add carrots, mushrooms, or pearl onions during the last 2 hours of cooking so they don’t get mushy.

4. Can I freeze the leftovers?

Absolutely. Cool completely, portion into containers, and freeze for up to 3 months. Thaw in the fridge overnight and reheat gently.

5. How do I thicken the sauce?

If the sauce is too thin after cooking, stir in a cornstarch slurry (1 tsp cornstarch + 1 tbsp water) and cook on high for 15–20 minutes.

6. Can I use ghee instead of butter?

Yes. Ghee works wonderfully and adds a slightly nuttier flavor, making it a great lactose-free option.

7. How long will leftovers last in the fridge?

Store in an airtight container in the fridge for up to 4 days. Reheat in the microwave or on the stovetop.
