Cooking Steps
• Boil the kettle. Half-fill a large saucepan with boiling water, then add a generous pinch of salt. • Peel potato and carrot and cut into bite-sized chunks. Peel garlic cloves. • Cook potato, carrot and garlic in the boiling water, over high heat, until easily pierced with a fork, 12-15 minutes. Drain and return to the pan. • Add the butter and milk to the veggies and season with salt. Mash until smooth. Cover to keep warm.
TIP: Save time and get more fibre by leaving the potato unpeeled.
• Meanwhile, thinly slice button mushrooms and onion (see ingredients). • Halve any thicker stalks of baby broccoli lengthways. Slice lemon into wedges.
• In a large frying pan, heat a drizzle of olive oil over medium-high heat. Cook baby broccoli until tender, 5-6 minutes. • Transfer to a bowl, add a squeeze of lemon juice and season to taste. Cover to keep warm and set aside.
• Return frying pan to medium-high heat with a drizzle of olive oil. Cook mushrooms and onion, stirring, until tender, 6-7 minutes. • Add garlic & herb seasoning and cook, until fragrant, 1 minute.
• Add cream (see ingredients), dijon mustard (see ingredients) and a splash of water. Simmer, until slightly reduced, 2-3 minutes. Season to taste.
• Divide veggie mash, creamy mushroom casserole and lemony baby broccoli between plates. • Serve with any remaining lemon wedges. Enjoy!
