Can I use a different cut of beef?

Yes. Chuck roast is ideal because it’s marbled and tenderizes beautifully, but you can also use brisket or bottom round roast. Just make sure to cook long enough for the beef to fall apart easily.

Do I have to sear the beef first?

It’s optional, but highly recommended. Searing locks in flavor and adds that deep caramelized taste that makes the gravy extra rich.

Can I make this recipe gluten-free?

Absolutely. Just use a gluten-free soy sauce or tamari, and ensure your beef broth is gluten-free. The flavor stays just as delicious.

What can I use instead of mushrooms?

If you’re not a mushroom fan, try adding extra onions or even diced carrots for a milder sweetness.

How do I make the gravy thicker?

Mix 1 tablespoon cornstarch with 2 tablespoons cold water, then stir it into the slow cooker during the last 30 minutes of cooking. It’ll thicken as it simmers.
