Savory and hearty low carb vegetable beef soup is a one bowl meal that will keep your belly warm and full on a cold night!
In a stock pot or Dutch oven, melt 2 tablespoons butter over medium high heat. Brown the beef in batches, about 3 to 4 minutes. Transfer browned beef to a plate or bowl.
Reduce heat to medium and add remaining 2 tablespoons of butter. Add the onion, carrot, and garlic and sauté until translucent, about 2 to 3 minutes.
Add 1 cup of the beef broth and scrape up any brown bits (deglaze). Add remaining broth after the pan is deglazed.
Add all remaining ingredients to the pot. Return the beef to the pot too. Stir to combine.
