This is a beef mince casserole built around a sherry-and-broth sauce that tastes like it cooked all afternoon — but the whole thing is done in 35 minutes. The broiler step at the end gives the top a lightly caramelized crust that you just don’t get from a stovetop-only dish. If you need a filling, no-fuss dinner that scales easily for a crowd, this is a smart pick.
Why this recipe works
Two things make this casserole work. First, the flour goes in dry — straight onto the browned meat and onions — before any liquid is added. That brief toasting step cooks out the raw flour taste and means your sauce thickens evenly instead of going lumpy. Second, the sherry and broth are added together and simmered until slightly reduced before the mushrooms and tomato paste go in. That sequence concentrates the savory base early, so the final sauce has real depth without needing a long cook time. The broiler finish is not just cosmetic — a few minutes of direct heat tightens the top layer and adds a faint caramelized note that makes the dish taste more complete.
Shopping notes
- Dry sherry: Look for a bottle labeled “dry” or “fino” — cooking sherry sold near the vinegars works but tends to be saltier, so hold back on added salt until you taste the finished sauce. A half-cup bottle is not a thing; buy a standard 375 ml bottle and the rest keeps well in the fridge for weeks.
- Beef mince: An 80/20 blend gives the sauce more body than leaner mince, which can turn grainy. Drain excess fat after browning if the pan looks oily before you add the flour.
- Mushrooms: Cremini (baby bella) mushrooms hold their texture better than white button mushrooms after simmering and broiling. Either works, but cremini are worth grabbing if you see them.
Common problems and fixes
- Sauce is too thin after simmering: Let it go another 2–3 minutes uncovered before transferring to the casserole dish. The sauce thickens further under the broiler, so don’t panic if it looks slightly loose on the stovetop.
- Top burns under the broiler before it caramelizes: Broiler intensity varies a lot by oven. Position the rack so the dish sits about 6 inches from the element, and check it at the 2-minute mark. Pull it the moment the surface turns golden.
- Meat clumps instead of browning: The pan wasn’t hot enough, or it was overcrowded. Use a wide skillet so the mince has room to spread. Don’t stir for the first 2 minutes — let it sit and sear.
- Sauce tastes flat: The sherry didn’t cook long enough and the alcohol is still sharp. Make sure the mixture reaches a real simmer and stays there for the full 5 minutes before you add the mushrooms.
- Scaling up for guests and the sauce seems thin: When doubling the recipe, use the same amount of flour (1 tablespoon per pound of mince) and extend the initial simmer by 3–4 minutes — a larger volume of liquid takes longer to reduce. Skip the garnish — not worth the extra dish when you’re plating for eight.
Storage and reheating
Leftovers keep in an airtight container in the fridge for up to 3 days. The sauce thickens considerably when cold, which is normal — add a splash of beef broth when reheating to loosen it. Reheat on the stovetop over medium-low heat, stirring occasionally, for about 5 minutes; the microwave works too but stir halfway through to avoid hot spots. This casserole freezes well for up to 2 months. Freeze it without the parsley garnish, in a sealed freezer-safe container, and thaw overnight in the fridge before reheating.
Beef Mince and Sherry Casserole
Equipment
- Medium skillet
- Wooden spoon
- Oven-safe casserole dish
- Sharp knife
- Cutting board
Ingredients
- 2 tablespoons olive oil preferably extra virgin
- 1 pound beef mince preferably grass-fed
- 1 medium onion finely chopped
- 2 cloves garlic minced
- 1 cup beef broth preferably low-sodium
- ½ cup dry sherry
- 1 tablespoon flour all-purpose
- 1 teaspoon salt to taste
- ½ teaspoon freshly ground black pepper to taste
- 1 cup mushrooms sliced
- 1 tablespoon tomato paste
- 1 piece bay leaf
- 2 tablespoons parsley freshly chopped, for garnish
Instructions
- 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.

Frequently asked questions
Can I make this ahead and reheat it for a dinner party?
Yes — it reheats very well and the flavors are actually better the next day. Make it through the broiler step, cool completely, refrigerate, then reheat gently on the stovetop with a splash of broth to loosen the sauce before serving.
What can I serve this over to stretch it further for a larger group?
Egg noodles or mashed potatoes are the most practical options — both absorb the sauce well and are easy to cook in big batches. Rice works too, though it soaks up liquid faster, so serve immediately once plated.
Do I have to use an oven-safe dish, or can I skip the broiler step?
You can skip it — the casserole is fully cooked before it goes under the broiler. The broiler just adds a slightly firmer, browned top layer; without it, the dish is saucier and softer throughout, which is still good.
Can I double or triple this recipe without changing anything else?
Doubling works without major adjustments, but use your largest skillet or do the browning in two batches so the meat actually browns instead of steaming. Triple batches are easier to finish in a roasting pan under the broiler rather than a standard casserole dish.
