Beef Meatloaf with Tomato and Mustard Glaze

Allow 12 minutes to measure the ingredients, dice the onion and grate the garlic, beat the eggs and line a deep-rimmed metal tray at least 35 x 25cm with baking parchment. Do not switch on the oven yet: preheating has its own later stage. Keep the fully thawed beef mince chilled until mixing. Have a clean food thermometer ready; do not taste the raw mixture.

Allow 2 minutes to heat the rapeseed oil in a medium frying pan over a medium-low heat. Add the onion and cook for 9 minutes, stirring, until soft and translucent with a little colour at the edges, not dark brown. Add the garlic and stir for 1 minute. If the onion is still firm, continue until soft; extra softening time extends the cooking and total estimate.

Allow 1 minute to spread the onion and garlic on a plate, then leave for 10 minutes, or longer until no longer warm. Do not add hot onion to the raw beef or eggs. Extra cooling time extends preparation and total time.

Now heat the oven to 180°C, 160°C fan, gas 4. Allow an estimated 20 minutes for switching it on, heating and checking readiness; wait until its preheat indicator shows it has reached the set temperature. Do not hydrate, mix or shape during this separately budgeted preheat stage: the timetable does not credit any overlap. Keep the mince refrigerated. If the oven needs longer, the extra wait extends preparation and total time. Leave the oven at this setting for the subsequent baking stages.

Put the fresh breadcrumbs and milk into the large mixing bowl. Stir and leave for 5 minutes until the crumbs have absorbed the milk and form a soft, damp mixture rather than floating in liquid.

Allow 10 minutes for mixing, shaping and cleaning up after handling raw meat. Add the beef mince, cooled onion and garlic, beaten eggs, Worcestershire sauce, thyme, salt and black pepper to the damp breadcrumbs. Work together with clean hands just until evenly combined and cohesive; avoid prolonged kneading. Shape on the lined tray into a broad rounded loaf approximately 26cm long and 12cm wide, with a maximum central height of about 6cm. Close large cracks without compressing it hard or forcing it into a precise rectangular shape. Leave space on every side for released juices. Wash your hands and clean utensils and surfaces after handling the raw mixture.

Allow 3 minutes to stir the tomato ketchup, Dijon mustard, cider vinegar and light brown sugar together in a small bowl. Keep this separate from raw-meat utensils; all of it is for glazing the loaf later.

Allow 1 minute to check the oven is still at temperature and load the tray onto the middle shelf. Bake uncovered for an estimated 50 minutes. The surface should look set and lightly browned, and some fat and juices may collect around it. These are surface cues, not proof that the centre is cooked.

Allow 3 minutes to remove the tray to a heatproof surface with oven gloves, spread all the glaze over the top and upper sides using a clean spoon or brush, and return the tray to the oven. This allowance includes both transfers and any foil adjustment. Bake for an estimated 25 minutes; the glaze should be glossy and darkened at the edges, not black. Loosely cover the top with foil if it is colouring too quickly.

Allow 3 minutes for taking the tray onto a heatproof surface, checking several central spots and returning it to the oven. Insert a clean food thermometer from the side into the thickest centre without touching the tray and use the coolest reading. Clean the probe after each use and between checks, especially after an undercooked reading; remove an instant-read thermometer between readings and before returning the tray. Only a purpose-designed oven-safe probe may remain in the oven. If any checked central spot is below 70°C, bake for a further 5 minutes, then allow another 3 minutes for removal, clean-probe checks and oven return. Repeat as needed; each extra bake-and-check cycle adds 8 minutes to the estimate, not a guaranteed maximum. Do not serve a rare centre or judge safety by the glaze colour.

Only when every checked central spot is at least 70°C, return the tray to the hot oven and start a 2-minute timer once it is back inside. Keep cooking for at least those 2 minutes to maintain the centre at or above 70°C. The preceding checking allowance covers the return transfer, not this hold. Then allow 3 minutes to take the tray to a heatproof surface and recheck the central spots with a clean probe, cleaning it after each use; this allowance also includes returning the tray if a check fails. All must still read at least 70°C. If any is below 70°C, return the tray, give it another 5-minute bake and 3-minute checking cycle, and repeat the full 2-minute oven hold and 3-minute final recheck once all spots reach 70°C. If an oven-safe continuous probe shows the temperature falling below 70°C during the hold, restart the full hold only once it has recovered. The safety endpoint takes priority over the estimated timetable.

After successful final checks, allow 1 minute to settle the tray safely out of the oven and clean the probe and checking area. Rest the loaf on its tray for 15 minutes. Resting is not a substitute for the oven safety hold. Allow 5 minutes to lift it carefully with two wide spatulas, cut with a sharp knife into eight portions and plate. Serve promptly with mashed potatoes and steamed green beans; accompaniments are separate from the recipe quantities and timings. The total estimate ends at plated service, not merely at the end of resting.
