In a large Dutch oven, heat 2 tablespoons of oil until hot over medium heat. Add carrots, celery, onion, and 2 tablespoons of butter. Sauté the vegetables until almost tender, about 5 minutes, stirring often.
2 tablespoons vegetable oil, 3 carrots, 2 ribs celery, 1 yellow onion, 10 tablespoons unsalted butter
Add garlic; stir and cook for 30 seconds. Transfer vegetables to a plate; set aside.
2 cloves garlic
Add the ground chuck and sirloin steak to the pot and cook, stirring often, just until the meat is brown. Transfer the browned meat to the same plate as the vegetables and discard any rendered fat. Wipe out the pot with a paper towel.
1 pound ground chuck, 2 pounds sirloin steak
In the same pot, melt ½ cup of butter and whisk in 1 cup flour until smooth to make a roux. Cook over medium heat until the flour mixture is a little darker and thicker.
1 cup all-purpose flour
Whisk in the beef broth, water, and wine, stirring until smooth.
29 ounces unsalted beef broth, 6 cups water, ¼ cup red wine
Add the Ac'cent, beef broth concentrate, frozen vegetables, tomatoes, and black pepper.
1 tablespoon Ac'cent seasoning, 2 teaspoons beef stock concentrate, 10 ounces frozen mixed vegetables, 14.5 ounces petite diced tomatoes, 1 teaspoon ground black pepper
Bring to a boil, stirring often, over medium heat, then reduce heat to low.
Add back the sauteéd vegetables and beef, stirring occasionally, until the liquid has thickened and the frozen vegetables have softened.
Simmer the soup 1-2 hours.
Serve with crusty bread and a lovely, crisp, green salad.
