Christmas dinner for two works best when it feels like a complete meal in its own right. You do not need a miniature version of every dish served at a large family gathering. One good main, two favourite sides and a pudding you both want are enough to make the occasion feel special.
This vegetarian menu centres on mushroom and lentil pot pies, with crisp roast potatoes and orange-scented carrots. It uses familiar supermarket ingredients and gives you a reason for everything on the shopping list. Choose pastry and stock labelled suitable for vegetarians, and check all ingredients against any dietary requirements.
Plan a small meal with one focal point
Start with the dish you are most looking forward to eating. Here, individual pastry-topped pies provide the centrepiece, so there is no need for a second elaborate main or several rich accompaniments.
Serve something light beforehand only if you want it. A small bowl of soup or a few olives will leave room for dinner. For pudding, two individual portions can be easier than a whole dessert bought because it looks festive.
Check your oven space before cooking. The pies need two ovenproof dishes of approximately 350ml each. The potatoes and carrots can share a roasting tray if it is large enough to leave them in a single layer.
Mushroom and lentil pot pies for two
Allow approximately 20 minutes for preparation, 15 minutes on the hob and 25 to 30 minutes in the oven. Timing will vary with your dishes, pastry and oven; use the appearance and temperature checks below as well.
Ingredients
You will need 1 small onion, finely chopped; 250g mushrooms, sliced; 1 garlic clove, finely chopped; 1 tablespoon olive oil; 1 tablespoon plain flour; 150ml vegetable stock; 150g drained, ready-cooked green or brown lentils; 1 teaspoon Dijon mustard; ½ teaspoon dried thyme; black pepper; approximately 150g ready-rolled puff pastry; and a little milk for brushing. Check the pastry pack’s cooking instructions before starting.
Method
Heat the oil in a wide frying pan over a medium heat. Add the onion and cook for about five minutes, stirring, until softened. Add the mushrooms and cook for another six to eight minutes, allowing the moisture they release to evaporate. Stir in the garlic for the final minute.
Sprinkle over the flour and stir for one minute. Gradually add the stock, then stir in the lentils, mustard, thyme and pepper. Simmer gently for three to five minutes until the filling is thick enough to spoon. Add a splash more stock if it becomes dry. Taste before deciding whether it needs salt.
Divide between the two ovenproof dishes, leaving a little room below the rims. Cut pastry lids slightly wider than the dishes. Lightly dampen the rims, lay the pastry over them and press to secure. Cut a small steam vent in each lid and brush lightly with milk.
Put the dishes on a baking tray and bake in a preheated oven at 200°C, or 180°C fan, for approximately 25 to 30 minutes, adjusting to the pastry manufacturer’s instructions where necessary. The pastry should be well risen and golden and the filling steaming hot throughout. Give the pies a few minutes to settle before serving, as the filling will be very hot.
Roast potatoes and orange carrots
For two people, use 400g potatoes, 250g carrots, 1½ tablespoons olive oil, the finely grated zest of half an orange and black pepper. Add a small pinch of salt if wanted.
Peel the potatoes and cut them into similarly sized chunks, approximately 3cm across. Simmer in water for eight to ten minutes until the outside begins to soften. Drain well, leave to steam-dry briefly and shake gently in the saucepan to roughen the edges.
Cut the carrots into batons of similar thickness. Toss the potatoes with one tablespoon of oil and the carrots with the remaining half tablespoon, orange zest and pepper. Spread across a roasting tray, keeping the vegetables in separate areas so they are easy to turn.
Roast at 200°C, or 180°C fan, for approximately 40 to 50 minutes, turning halfway through. Check earlier if the pieces are small. The potatoes should be golden and tender inside, and the carrots tender with lightly coloured edges. Remove the carrots first if they are ready before the potatoes.
Bring everything to the table together
Make the pie filling while the potatoes are parboiling. Put the vegetables into the oven first, then assemble the pies. Add the pies when the vegetables have approximately half an hour left, leaving space for hot air to circulate.
Use the final few minutes to warm the plates and set the table. Check each dish rather than relying on a rigid minute-by-minute countdown. If the vegetables finish first, they can wait briefly in a warm serving dish while the pastry completes its cooking.
The pies already contain a sauce. If you prefer gravy, make a small amount separately rather than buying a large extra container with no planned use.
Buy for two, with a plan for the rest
A tin or pouch of lentils may contain more than this recipe needs. Put the remainder into a suitable covered container, refrigerate and follow the opened-pack storage instructions. They can be added to another meal within the permitted storage period.
The same principle applies to pastry. Check whether the unused portion can be frozen and follow the pack instructions. Do not assume that every previously frozen product is suitable for freezing again.
If you have cooked leftovers, cool and refrigerate them within two hours, then eat within 48 hours or freeze promptly. Reheat leftovers only once, until steaming hot throughout, following Food Standards Agency advice.
A small Christmas dinner gives you the freedom to cook exactly what you enjoy. Set the table properly, give the main dish your attention and leave out the extras that neither of you will miss.
