This is a ground beef casserole cooked low and slow with dry sherry, tomato passata, and diced potatoes — everything in one pot, no sides needed. It takes about two hours start to finish, but most of that is hands-off simmering time. The main reason to make it: it reheats better than it tastes fresh, which makes it one of the more useful things you can cook on a Sunday.
What makes this version work
Two things matter here. First, browning the mince properly — not just until it changes color, but until the liquid it releases has fully evaporated and the meat starts to fry in the fat. That takes a full 10 minutes and builds the savory base the whole dish depends on. Second, simmering the sherry for 2–3 minutes before adding the other liquids. That short cook-off removes the sharp alcohol edge and lets the sherry’s flavor fold into the beef rather than sit on top of it. Skip either step and the casserole tastes flat.
Substitutions that actually work
- Dry sherry: A dry Marsala works well. Dry white wine is a reasonable fallback but gives a lighter, less nutty result. Avoid cream sherry — it makes the dish noticeably sweet.
- Tomato passata: Crushed canned tomatoes are a direct swap. Drain off some of the liquid if the brand runs watery, or the casserole can end up thin.
- Beef stock: Chicken stock works in a pinch. Use low-sodium either way — the passata already carries salt.
- Potatoes: Waxy varieties like Yukon Gold hold their shape better after an hour of simmering than russets, which can go mushy.
Troubleshooting
- Casserole is watery after an hour: Remove the lid for the last 15 minutes and turn the heat up slightly to reduce the liquid. This is more common with passata brands that have high water content.
- Potatoes still firm after an hour: Your dice was probably larger than 1 inch, or the heat was too low. Cut them smaller next time. For now, just keep simmering with the lid on — check every 10 minutes.
- Beef is clumping in large chunks: It wasn’t broken up enough during browning. Use a wooden spoon or potato masher to break the mince apart while it cooks. Large clumps don’t absorb the braising liquid evenly.
- Dish tastes thin or one-dimensional: Check that the sherry actually simmered long enough before you added the other ingredients. Also confirm the mince was fully browned — gray, steamed mince adds no depth.
- Casserole scorching on the bottom: The heat is too high. Ground beef casseroles need a genuine low simmer — small bubbles, not a rolling boil. A heavy-bottomed pot also helps distribute heat more evenly.
Make-ahead notes
This casserole is genuinely better the next day — the sherry and herbs settle into the sauce overnight. Cool it completely before refrigerating, and store it in an airtight container for up to 4 days. For longer storage, freeze in individual portions for up to 3 months; the potatoes soften slightly after freezing but hold together well enough. Reheat on the stovetop over medium-low heat with a splash of beef stock or water to loosen it — about 8–10 minutes, stirring occasionally. If reheating from frozen, thaw overnight in the fridge first. Skip the parsley garnish if you’re prepping containers for the week — not worth the extra dish.
Beef Mince and Sherry Casserole
Ingredients
2 tablespoons olive oil - extra virgin for a rich flavor
1 large onion - chopped finely
2 cloves garlic - minced
500 grams ground beef (minced beef) - preferably grass-fed for better flavor- 1 cup sherry - dry, for depth of flavor
- 400 grams tomato passata
1 teaspoon dried thyme
1 teaspoon dried oregano
1 piece bay leaf
1 cup beef stock (beef broth or beef bouillon) - low sodium preferred
2 cups potatoes - peeled and diced into 1-inch cubes
2 tablespoons parsley - fresh, chopped for garnish
Instructions
- Heat the olive oil in a large casserole pot over medium heat. Add the chopped onions and sauté until translucent, about 5 minutes.
- Add the minced garlic and stir for another minute until fragrant.
- Add the beef mince to the pot. Cook, stirring occasionally, until the meat is browned and any liquid has evaporated, approximately 10 minutes.
- Pour in the sherry and simmer for 2-3 minutes to allow the alcohol to cook off, melding well with the beef.
- Stir in the tomato passata, dried thyme, dried oregano, bay leaf, and beef stock. Bring to a gentle simmer.
- Add the diced potatoes, cover the pot with a lid, and reduce heat to low. Let the casserole simmer for 1 hour, stirring occasionally, until the potatoes are tender and the flavors meld.
- Remove the bay leaf, season with salt and pepper to taste, and garnish with freshly chopped parsley before serving.

Common questions
Does the sherry flavor come through strongly in the finished dish?
No — it’s present but not dominant. After simmering with the passata and stock for over an hour, the sherry contributes a mild nuttiness and a bit of depth rather than a distinct wine flavor. If you want it more pronounced, add a small splash in the last 10 minutes of cooking.
How do I know the ground beef is fully cooked and safe to eat?
Ground beef is safe at an internal temperature of 160°F (71°C). In a casserole like this, the mince is fully browned before the liquid goes in, and then it simmers for another hour — it will be well past that temperature. If you want to confirm, a meat thermometer inserted into the thickest part of the mixture should read at least 160°F.
Can I make this in a slow cooker instead?
Yes, with one adjustment: still brown the mince and cook off the sherry on the stovetop first, then transfer everything to the slow cooker. Cook on low for 6–7 hours or high for 3–4 hours. Skipping the browning step in a slow cooker produces a noticeably blander result.
What’s the best way to portion this for lunches during the week?
Let the casserole cool fully, then divide it into airtight containers — it portions cleanly once it has set. Six servings fit comfortably in standard 2-cup meal prep containers, and each one reheats in about 3 minutes in the microwave with a loose lid to prevent splattering.
Can I double the recipe without changing the cooking time?
You can double the ingredients, but plan for the browning step to take longer — crowding the pot causes the mince to steam rather than brown, so work in batches if needed. The simmering time stays roughly the same once everything is combined, though a larger volume may need an extra 10–15 minutes for the potatoes to fully soften.
Will this work with a leaner ground beef, like 90/10?
It works, but the sauce will be slightly less rich. Leaner mince also has less fat to help with browning, so add a touch more olive oil to the pan if the meat starts sticking. The flavor difference is minor once everything has simmered together.
