Instructions

1. 1

   Prepare the ingredients

   Chop the parsley, slice the onion and finely chop the garlic cloves. Quarter the mushrooms and set them aside.

2. 2

   Brown the mushrooms

   Heat a wide pan over medium-high heat and add the olive oil. When it is hot, add the mushrooms in a single layer. Stir occasionally and cook for 2–3 minutes.

3. 3

   Add butter and aromatics

   Add the butter and cook for another 2–3 minutes, stirring, until the mushrooms are golden and their moisture has evaporated. Add the sliced onion and chopped garlic, then sauté for 1–2 minutes until the garlic is fragrant and the onion is slightly soft.

4. 4

   Season the mushrooms

   Add the salt, red pepper flakes, dried herbs and black pepper, then toss to combine. Turn off the heat, add the lemon juice and chopped parsley, and toss again.

5. 5

   Mix the sauce

   Put all the sauce ingredients in a bowl and whisk until smooth, thick and creamy. Taste and adjust the salt or lemon if needed, then chill for 10 minutes for the best texture.

6. 6

   Plate and serve

   Spoon the yoghurt sauce onto a wide plate and spread it gently with the back of a spoon. Pile the hot mushrooms on top, slightly off-centre, and finish with a pinch of black pepper and chopped parsley. Serve with toasted bread, naan or flatbread.

What are butter garlic mushrooms?

They are a simple pan-cooked mushroom dish built around the familiar pairing of butter and garlic. This American-style version serves the mushrooms over a seasoned yoghurt sauce, so the plate combines rich, savoury topping with a cool, tangy base.

The method works because the mushrooms are browned before the onion and garlic go in. That gives them a chance to colour without the aromatics spending too long in the hot pan.

Nutrition and macros by portion

The nutrition label shows one serving as written: 320 calories, 0g protein, 0g carbs, 0g fat.

The mushrooms and onion provide most of the carbohydrates, while the olive oil, butter and yoghurt contribute much of the fat; the yoghurt also supplies some protein. For a more balanced plate, serve a measured portion with a generous side of vegetables and bread or flatbread to suit your appetite.

Choosing the mushrooms

Button mushrooms: These have a mild flavour and cook quickly once quartered. Choose firm mushrooms and clean them before cutting.

Cremini mushrooms: These are a good alternative if you want a deeper, earthier flavour. Keep the pieces roughly even so they cook at a similar pace.

Getting a good sear

Room in the pan: Arrange the mushrooms in a single layer so they have contact with the hot surface. If they are crowded, they are more likely to release moisture and steam rather than brown.

Wait for the butter: The mushrooms cook first in olive oil, then the butter goes in for the second stage. Stir occasionally, and look for golden surfaces and evaporated moisture before adding the onion and garlic.

Timing the aromatics

Garlic and onion: Add them after the mushrooms have browned, then sauté for just 1–2 minutes. The garlic should smell fragrant and the onion should soften slightly without taking on too much colour.

Finish off the heat: Lemon juice and parsley go in after the pan is switched off. This keeps the finishing flavours fresh while the mushrooms are still hot.

Making the yoghurt sauce

Thick yoghurt: Greek-style or strained yoghurt gives the sauce enough body to hold its shape on the plate. Whisk it with the garlic, lemon, oil, herbs and seasonings until smooth.

Chill time: Rest the sauce in the fridge for 10 minutes as directed. Taste it before serving and adjust the salt or lemon if needed.

Serving the dish

Spread the sauce across a wide plate, then pile the mushrooms slightly off-centre so both layers remain visible. A little black pepper and parsley make a simple final garnish.

Toasted bread, naan or flatbread works well for scooping up the mushrooms and sauce. Serve the mushrooms hot while the yoghurt sauce is cool.

Recipe notes & tips

• Cut the mushrooms into similarly sized quarters so they cook evenly.
• Use a wide pan and arrange the mushrooms in a single layer for better browning.
• Stir the mushrooms occasionally rather than constantly to give them time to colour.
• Add the garlic only after the mushrooms have browned to help prevent it from burning.
• Chill the sauce for 10 minutes while you finish the mushrooms.
• Serve the mushrooms straight from the pan while they are hot.

Variations

• Make it vegan: Use plant-based butter and a thick unsweetened plant-based yoghurt.
• Change the herbs: Use oregano instead of dried mixed herbs in the mushroom seasoning.
• Adjust the heat: Reduce or leave out the red pepper flakes for a milder dish.
• Add extra lemon: Stir a little more lemon juice into the sauce if you prefer a sharper flavour.
• Choose another side: Serve with toasted sourdough or flatbread instead of naan.

Common mistakes to avoid

• Crowding the pan: The mushrooms may steam instead of brown; use a wide pan and keep them in a single layer.
• Adding garlic too early: It can burn before the mushrooms are ready; add it with the onion after browning.
• Stirring constantly: The mushrooms need contact with the pan to colour; stir only occasionally.
• Leaving excess moisture: Wait until the liquid has evaporated and the mushrooms are golden before adding the onion.
• Serving the sauce straight away: It may be less thick and settled; chill it for 10 minutes as directed.

How to store

Store leftover mushrooms and yoghurt sauce separately in airtight containers in the fridge and use within 3 days. Reheat the mushrooms gently in a pan until hot; serve the sauce cold rather than reheating it.
