FAQs
What’s the best cut of beef for pot roast?
Chuck roast is ideal because it becomes tender and flavorful when slow-cooked.
Can I skip searing the beef?
Searing enhances flavor, but you can skip it if short on time.
What type of onions should I use?
Yellow onions caramelize best, but white or sweet onions work too.
Can I use a different cheese?
Yes! Gruyère, Swiss, or provolone work well for a melty topping.
Can I make this ahead of time?
Yes! It actually tastes better the next day as the flavors deepen.
How do I thicken the sauce?
Mix a tablespoon of cornstarch with cold water and stir it into the broth before serving.
What sides go well with this dish?
Mashed potatoes, crusty bread, egg noodles, or roasted vegetables pair perfectly.

Yes, but homemade caramelized onions provide the best flavor.

Use low-sodium broth and adjust the Worcestershire sauce to taste.
