Dry sherry adds a subtle savory depth to this beef mince casserole, rounding out the rich tomato and herb base. Everything simmers together quickly, making it a practical choice for a 30-minute dinner with a slow-cooked feel. Serve it over rice, pasta, or with crusty bread to soak up the sauce.
Heat the olive oil in the skillet over medium-high heat. Add the beef mince, breaking it apart with a wooden spoon until browned, about 5-7 minutes.
Add the chopped onion and minced garlic to the skillet. Sauté until the onion is translucent and fragrant, approximately 3-4 minutes.
Sprinkle in the flour and stir well, allowing the flour to coat the meat and onions completely.
Gradually stir in the beef broth and dry sherry. Bring to a simmer and let the mixture thicken slightly, about 5 minutes.
Season with salt and black pepper, then add the mushrooms, tomato paste, and bay leaf. Let it simmer for another 5 minutes, ensuring the flavors meld together.
Transfer the contents to an oven-safe casserole dish and place under a preheated broiler for 3-4 minutes, watching closely to avoid burning, until the top is slightly caramelized.
Garnish with freshly chopped parsley before serving.
Notes
For an enriched flavor, consider adding a splash of Worcestershire sauce.
If sherry is unavailable, a dry white wine could suffice though will impart a different flavor profile.
To thicken the sauce quickly, use a dash of cornstarch instead of flour.
