Frequently Asked Questions

What is the best cut of meat for this casserole? Beef chuck is highly recommended because it becomes incredibly tender after a long slow cook. However, if you are short on time, sirloin works well too.

Can I make this without a slow cooker? Yes! You can cook this in a Dutch oven on the stove or in the oven at 300°F (150°C) for about 2.5 to 3 hours until the beef is fork-tender.

Can I substitute the heavy cream? For a lighter version, you can use half-and-half or even full-fat Greek yogurt, though the texture won't be quite as silky as the heavy cream version.
