In a large skillet over medium-high heat, cook the ground beef 5–7 minutes until browned. Drain excess fat. Add the chopped onion and sauté 5–6 minutes until translucent, then stir in the garlic for the last minute.

Step 4: Make the Gravy
Sprinkle the flour over the beef mixture and cook for 1 minute. Gradually pour in the beef broth, stirring constantly to prevent lumps. Simmer 3–5 minutes until the gravy thickens enough to coat the back of a spoon.

Step 5: Season and Add Veggies
Stir in salt, pepper, and curry powder if using. Fold in the peas and carrots and cook 2–3 minutes until heated through.

Step 6: Serve
Spoon a generous portion of mashed potatoes into a bowl and top with a ladle of the hot ground beef gravy. Serve immediately.
