Start by patting the chuck roast dry with paper towels. This helps it to sear and develop a rich, brown crust.
In a large frying pan, warm up 2 tablespoons of oil over medium-high heat. Sear the chuck roast on all sides until it’s nicely seared—about 2–3 minutes per side. Once seared, transfer the roast to your crockpot.
In the same pan, using the leftover oil and browned bits from the beef, add the chopped onion and sauté for about 4 minutes, until it’s soft and fragrant.
Now stir in the can of diced tomatoes, 1 tbsp garlic powder, 3 tbsp tomato paste, and 4 tbsp sweet Hungarian paprika. Let it all warm through for a minute or two.
Next, pour in the 1¾ cups of beef broth, toss in the bay leaf, and sprinkle in the 2 tbsp of cornstarch. Add salt and pepper to taste. Stir well until everything is combined and starting to simmer. Taste the sauce at this point and adjust the salt or paprika if needed.
Once the sauce is bubbling, pour it all over the seared chuck roast in the crockpot. Make sure the roast is mostly submerged in the sauce—that’s what helps it cook evenly and stay moist.
Set your crock pot on LOW and cook for 8 hours. By the end of the day, your beef will be fork-tender.
Once the goulash is ready, remove the bay leaf and shred the beef with a couple of forks right in the crockpot. It should come apart easily.
Serve the goulash over a bed of egg noodles, or go rustic with mashed potatoes, rice, or even spaetzle.
