Pat the meat dry: Using paper towels, pat the beef dry with paper towels. If using stew meat and any pieces of meat are very large, cut them into smaller 1-inch cubes. If using a whole chuck, be sure to trim off any pieces of excess fat before cutting into cubes or slicing.
2 lbs. stew meat or a boneless chuck roast
Season: Add the seasonings to the meat and stir to coat all pieces of meat.
1½ tsp. kosher salt, 1 tsp. garlic powder, 1 tsp. onion powder, 1/4 tsp. pepper
Sear: Heat the olive oil in a large Dutch oven or pot over medium-high heat. Working in batches, sear the meat until browned on each side, usually a couple of minutes per side. Do not over-crowd the pan. Add more olive oil as necessary. Set the meat aside on a plate.
1-2 Tbsp olive oil
Sauté: Reduce the heat to medium-low and add the butter. Once melted, add the onions and cook for about 2-4 minutes. Add a pinch of salt, along with the garlic and cook for 30 seconds. Start Timer
1-2 Tbsp. unsalted butter, ½ yellow onion, 3 garlic cloves
Build flavor: Add the Worcestershire sauce, Dijon mustard, and tomato paste. Stir to combine.
1½ Tbsp Worcestershire, 1½ Tbsp. Dijon mustard, 1 Tbsp. tomato paste
Add stock: Stir in the beef stock, being sure to scrape all the browned bits on the bottom of the pan.
2 cups beef stock
Toss beef back in: Add the browned beef back into the pot, being sure to add in all the liquid at the bottom of the plate too, and bring to a gentle simmer.
Cook: Cover with a lid, and allow to simmer on low for 2 hours. You can give it a stir once or twice while it cooks to check in on it, making sure nothing is sticking to the bottom. Start Timer
Cook pasta: Once the beef is almost done, boil a large pot of salted water and cook pasta according to package directions, usually 5-7 minutes for medium egg noodles. Start Timer
8-12 oz. medium egg noodles
Make sour cream sauce: Once the beef is tender, in a bowl, whisk together the sour cream, 1/4 cup of the hot liquid from the beef, and cornstarch/flour to thicken. Whisk well. (The hot liquid helps to temper the sour cream so it doesn’t clump in the pot, so don’t skip this step).
2 cups full-fat sour cream, 3 Tbsp. cornstarch or flour
Add sauce to beef: Add sour cream mixture to the beef and stir to combine. Cook for a few minutes to allow the sauce to thicken but do not allow it to come to a boil.
Add noodles: Add cooked egg noodles and stir it all to combine.
Finish it up: Taste and adjust any seasonings as desired. Finish with parsley for a pop of color, and enjoy!
