Mushroom, pea and lemon couscous

Lemony couscous and mushrooms make a quick bowl with bright peas and herbs.

This recipe makes 4 servings and takes about 10 minutes to prepare plus 15 minutes to cook. Metric and imperial quantities are alternate measurements, so use one system rather than adding both. If you change the yield, keep the pan size and thickness of the food in mind: a crowded pan steams food and a deep baking dish can extend the cooking time.

Equipment

Set out large frying pan, heatproof bowl with lid, fork, zester. A wide pan gives moisture somewhere to evaporate; for an oven dish, leave space between pieces so heat can circulate. Use separate board and knife surfaces for raw protein and foods that will be eaten without further cooking.

Ingredients

You will need: couscous: 300 g (10½ oz); boiling vegetable stock: 360 ml (1½ cups); chestnut mushrooms, quartered: 350 g (12 oz); frozen peas: 150 g (5 oz); olive oil: 30 ml (2 tbsp); lemon zest and juice: 1 lemon (1 lemon); fresh thyme leaves: 5 g (1 tbsp); parsley, chopped: 15 g (½ oz). Gather the ingredients before heating the pan so the aromatics do not burn while a measurement is being found.

• couscous — 300 g / 10½ oz
• boiling vegetable stock — 360 ml / 1½ cups
• chestnut mushrooms, quartered — 350 g / 12 oz
• frozen peas — 150 g / 5 oz
• olive oil — 30 ml / 2 tbsp
• lemon zest and juice — 1 lemon / 1 lemon
• fresh thyme leaves — 5 g / 1 tbsp
• parsley, chopped — 15 g / ½ oz

Method

Read the full method once, then prepare the ingredients in the order listed. Keep raw and ready-to-eat ingredients separate, and wash hands and equipment after raw-protein contact.

Step 1

Put couscous in a heatproof bowl, pour over boiling vegetable stock, cover and leave for 8 minutes.

Step 2

Meanwhile heat olive oil in a frying pan and cook chestnut mushrooms with thyme until browned and tender.

Step 3

Add frozen peas to the mushrooms and cook for 3 minutes until hot and bright green.

Step 4

Fluff couscous with a fork, then fold in mushrooms, peas, lemon zest, lemon juice and parsley.

Step 5

Serve while the peas and couscous are hot.

Cooking and safety check

Use freshly boiled stock and heat the peas until steaming before serving. A time estimate and a browned surface do not prove that the centre is cooked. Use a suitable food thermometer where the ingredient or local guidance requires one, and follow the package or official instructions for the specific food.

Substitutions that respect the dish

A substitution should preserve the recipe’s job, not merely its colour. Use quinoa in place of couscous, cooking it separately; quinoa is naturally gluten-free. Use mint instead of parsley. Use broccoli florets instead of frozen peas, steaming them until tender.

Allergen notes

This recipe contains or may contain gluten, celery may be present in packaged stock. Check every packaged ingredient because formulations and cross-contact warnings vary.

Common mistakes and how to correct them

Use one troubleshooting change at a time. If the centre is undercooked, return it to the appropriate heat and check again rather than relying on the outside colour. If the pan is dry, add liquid gradually; if it is watery, reduce uncovered. Texture may also reflect crowded equipment, a different ingredient size, or a changed batch quantity.

• Keep the bowl covered while couscous hydrates.
• Let mushrooms colour before stirring them.
• Add lemon juice after cooking so its flavour stays fresh.

Leftovers and storage

Refrigerate within two hours for up to two days. Reheat in a covered pan with 30 ml (2 tbsp) vegetable stock until steaming.
