This butter beans and mushrooms on toast recipe makes a quick lunch or easy dinner with simple ingredients and very little prep. Creamy butter beans create a filling base, while mushrooms add a savory topping that works well with crisp sourdough. The mix of textures keeps the dish interesting without making it complicated. Everything cooks in one pan, apart from the toast, which keeps cleanup manageable, too.
This recipe from Romy London builds flavor through small additions rather than heavy sauces. Lemon juice brightens the butter beans, while Italian seasoning and artichokes add depth. The mushrooms cook down with garlic and tamari until they become rich and slightly glossy. Once layered onto toasted sourdough, the combination feels hearty without becoming too heavy. A drizzle of balsamic glaze and some parsley finish everything with a little freshness.

Eat these beans and mushrooms on toast for lunch or dinner

Ingredients
- 2 slices sourdough bread
- 1 tbsp olive oil plus extra for toasting, if needed
- 1x 400 g tin butter beans drained and rinsed
- Juice of 1 lemon
- 1 tbsp Italian seasoning
- 2 tbsp grilled artichokes diced
- 250 g mushrooms sliced
- 1 pinch of salt
- 1 garlic clove grated or crushed
- 1 tbsp tamari or soy sauce
To serve (optional):
- 1-2 tbsp balsamic glaze
- Fresh parsley chopped
- Chili flakes
Instructions
- Toast the sourdough slices until golden and crisp. For extra flavor, heat a little olive oil in a skillet and toast the bread in the pan until lightly crisped on both sides.
- Place the drained butter beans in a shallow bowl. Add the lemon juice and mash roughly with the back of a fork – you’re looking for a chunky texture, not completely smooth. Stir in the olive oil and Italian seasoning, then fold through the diced artichokes. Set aside.
- Add the sliced mushrooms to a large frying pan with a small splash of water and a pinch of salt. Cook over medium heat until softened and any liquid has evaporated. Stir in the garlic and cook for 30 seconds, just until fragrant. Add the tamari and cook until the liquid reduces and coats the mushrooms.
- Spread the butter bean mash generously over the toasted sourdough. Top with the garlicky mushrooms, then drizzle with balsamic glaze if using. Finish with fresh parsley and a pinch of chili flakes.
