This stuffed marrow is a British-style baked marrow squash filled with seasoned beef, tomato, onion and breadcrumbs, then topped with cheddar. The mild, tender marrow balances the savoury filling, while a short first bake helps it soften without leaving the finished dish swimming in liquid.
Ingredients
- 1 large marrow, about 4 lb (1.8 kg)
- 1 tbsp olive oil (15 ml)
- 1 medium yellow onion, finely chopped, about 1 cup (150 g)
- 2 garlic cloves, finely chopped or crushed, about 2 tsp (6 g)
- 1 lb lean ground beef (450 g)
- 1 tbsp tomato paste (16 g)
- 1 can chopped tomatoes, about 14.5 oz (400 g), drained if very watery
- ¼ cup beef broth (60 ml)
- 1 tbsp Worcestershire sauce (15 ml)
- 1 tsp dried thyme (1 g)
- ½ tsp dried oregano (0.5 g)
- ½ tsp fine salt (3 g), plus more to taste
- ¼ tsp black pepper (0.5 g), plus more to taste
- ½ cup plain breadcrumbs (55 g)
- ¾ cup grated mature cheddar (85 g)
- 2 tbsp chopped fresh parsley (8 g), optional
Instructions
- Heat the oven to 375°F (190°C). Set a rack in the centre and lightly oil a large baking dish that will hold the marrow halves snugly. If your marrow is particularly long, cut each half crosswise so the pieces fit; keep the cut surfaces level to make filling them easier.
- Wash and dry the marrow, trim off the stem and flower ends, then cut it in half lengthwise. Scoop out the soft, seedy centre with a spoon, leaving a sturdy shell about ½ inch (1 cm) thick. Discard the seeds and pulp. If the centre is especially mature and fibrous, remove a little extra flesh, but do not scrape through the skin.
- Put the marrow halves cut-side up in the baking dish. Lightly season the flesh with a pinch of salt and pepper. Bake for 18–20 minutes, until it has begun to soften but still holds its shape. Carefully tip away any liquid that has collected in the hollows, using a spoon or oven mitts to steady the hot dish. Set the dish aside while you make the filling; leave the oven on.
- Meanwhile, warm the olive oil in a large frying pan over medium heat. Add the onion and cook for 5–7 minutes, stirring occasionally, until softened and translucent rather than browned. Stir in the garlic and cook for about 30 seconds, just until fragrant. If the garlic starts to colour quickly, lower the heat to avoid a bitter taste.
- Add the ground beef and break it into small pieces with a wooden spoon. Cook for 6–8 minutes, stirring and turning the meat, until no pink remains. Stir in the tomato paste, tomatoes, broth, Worcestershire sauce, thyme, oregano, salt and pepper. Let the mixture simmer for 5 minutes, stirring now and then, so it thickens slightly. Check the centre of the ground beef mixture with a food thermometer; USDA FSIS gives 160°F (71°C) as the safe minimum internal temperature for ground meat. Take the pan off the heat once it reaches that temperature.
- Stir the breadcrumbs into the beef mixture. They should soak up some of the tomato juices, leaving a moist filling that mounds on a spoon rather than running like a sauce. If the pan still looks very wet, simmer it for another minute or two before adding the crumbs. Taste a small spoonful and adjust the seasoning; remember the cheddar will add saltiness.
- Spoon the filling evenly into the marrow halves, pressing it gently into the hollows without packing it hard. A little filling may sit above the edges, but avoid making a tall mound that could spill as the marrow softens. Sprinkle the grated cheddar over the tops.
- Bake for 25–30 minutes, until the marrow is tender when pierced near the thickest part with a small knife and the cheese is melted and golden in places. If the top needs more colour, use the broiler for 1–2 minutes, watching closely. Rest the dish for 5 minutes before serving so the filling settles and the hot marrow is easier to portion.
Tips
- Choose a firm marrow. Look for unblemished skin and a squash that feels heavy for its size. A very large, over-mature marrow can have watery flesh and tough seeds; scoop out the whole seedy centre and expect it to need a few extra minutes in the oven.
- Control excess moisture. Marrow naturally releases water as it cooks. The short first bake and draining step help, and the breadcrumbs bind the tomato juices. Do not add extra broth unless the filling looks dry, or the finished dish may be soupy.
- Make the filling ahead if useful. Cook it, cool it promptly and refrigerate it in a covered container for up to 24 hours. Bring it out while the marrow starts its first bake, then fill and finish the dish. Do not leave cooked beef at room temperature for more than 2 hours.
- Use a baking dish that supports the halves. If they rock or roll, trim a very thin strip from the rounded underside to create a flat base. Take care not to cut through the shell, which would let the filling escape.
Serving Suggestions
Serve each person a generous piece of stuffed marrow while the cheese is still soft. Because the filling includes beef, tomatoes and breadcrumbs, it can stand as the centre of a meal; a simple green salad or steamed green beans add freshness without competing with its savoury flavour. For a more substantial plate, offer boiled or mashed potatoes, buttered new potatoes, or crusty bread to catch the juices.
If the marrow is exceptionally large, cut the baked halves into crosswise portions at the table rather than trying to lift each entire half onto a plate. A broad spatula helps support the soft shell. A spoon is useful for scooping up filling and tender marrow together. Keep extra parsley for a light garnish, and offer black pepper at the table.
Variations
Use lamb instead of beef: Replace the ground beef with 1 lb (450 g) ground lamb. Its fuller flavour works well with the thyme; cook it to 160°F (71°C), the USDA FSIS safe minimum for ground meat. Drain excess fat from the pan before adding the tomatoes if the lamb is fatty.
Make a vegetarian filling: Replace the beef with 2 cups (about 300 g) cooked brown lentils and 1 cup (150 g) finely chopped mushrooms. Cook the mushrooms with the onion until their liquid evaporates, then add the lentils and remaining filling ingredients. Use vegetable broth and a vegetarian Worcestershire-style sauce, or leave the sauce out; the result is earthy and softer than the meat version. Add a little extra breadcrumb if it seems loose.
Change the cheese or herbs: Use grated mature cheese such as Red Leicester in place of cheddar, keeping the amount the same. It melts similarly but gives a slightly sweeter finish. Fresh thyme can replace the dried herbs: use about 1 tbsp (3 g) leaves in total. Avoid adding a large amount of watery fresh tomato, which can thin the filling.
Add a little heat: Stir ¼ tsp (0.5 g) chilli flakes into the beef with the tomato paste, or add a finely chopped mild red chilli with the onion. Start modestly so the spice complements rather than overwhelms the mild marrow.
Storage and Reheating
Refrigerate leftovers within 2 hours of cooking. Once cool enough to handle, place portions in a shallow airtight container and keep them refrigerated for 3–4 days. For easier storage, cut the marrow into individual portions; the soft cooked shell is delicate, so lift each piece with a wide spatula.
Reheat portions in an oven-safe dish at 350°F (175°C), covered loosely with foil, until steaming hot throughout; uncover for the last few minutes if you want to refresh the cheese topping. The centre should reach 165°F (74°C), the USDA FSIS temperature for reheated leftovers, checked with a food thermometer. A microwave also works: cover the portion loosely, heat in short intervals, and check the middle for even heating. Avoid repeated cooling and reheating.
You can freeze cooked portions in a freezer-safe container for up to 2 months for best quality. Thaw overnight in the refrigerator, then reheat to 165°F (74°C). The marrow may be softer and release more liquid after freezing, but the filling should still be flavourful. Do not freeze a portion that has already been reheated.
Frequently Asked Questions
Do I need to peel the marrow?
No. The skin helps the halves keep their shape, and it softens as the marrow bakes. Trim away damaged areas, wash the outside well, and remove the seeds and stringy centre. If the skin is unusually tough on an older marrow, it is usually easier to scoop the cooked flesh from the shell while eating than to peel it before cooking.
How can I tell when the marrow is cooked?
Test the thickest part of the flesh with the tip of a small knife. It should enter with little resistance, while the shell still holds its shape. The exact time depends on the marrow’s size and maturity, so start checking near the end of the stated bake. The beef filling needs its own thermometer check at 160°F (71°C) before it goes into the marrow.
Why has my stuffed marrow turned watery?
Marrow contains a lot of water, and large, mature specimens can release more as they soften. Drain the liquid after the first bake, simmer the tomato filling until it is thick, and mix in the measured breadcrumbs. If liquid gathers in the dish during the final bake, carefully spoon or pour it away before serving.
Can I prepare stuffed marrow in advance?
Yes. Make the filling up to 24 hours ahead and refrigerate it covered. You can also bake the empty halves for the first 18–20 minutes, cool them promptly, and refrigerate them separately from the filling. Assemble and bake the dish when ready, adding a few minutes if the filling is cold. Keep cooked ingredients chilled and do not leave them at room temperature for more than 2 hours.
What can I use instead of breadcrumbs?
Use ½ cup (55 g) quick oats, or finely crushed plain crackers in the same quantity. Oats give the filling a slightly softer, less traditional texture; crackers make it saltier, so reduce the added salt. Add the substitute gradually and stop once the mixture is moist but no longer runny.
Can I cook this without cheese?
Yes. Leave off the cheddar and bake until the marrow is tender and the filling is hot. For a crisp top, sprinkle on a few extra breadcrumbs mixed with 1 tsp (5 ml) olive oil. The topping will be crunchy rather than creamy, and the dish will have a less rich finish.
