I first fell in love with setas de ostra al ajillo during a visit to L’Angleiru in the mountains of Asturias, Spain – a charming spot around 30 minutes from Gijón, this rustic Asturian gem served grilled wild mushrooms that were simply unforgettable.
When I finally got my hands on fresh British oyster mushrooms, I knew I had to recreate that magic at home. So here’s my interpretation: Garlic Butter Oyster Mushrooms served two ways — as little tapas over chickpeas in a tomato sauce and on sourdough toast. I promise, they were a total crowd-pleaser.
🌿 A Little History of Setas al Ajillo
Setas al ajillo — literally mushrooms with garlic — is a classic Spanish tapa that has been enjoyed for generations across the Iberian Peninsula. Like many Spanish dishes, its origins lie in simplicity and the use of seasonal, local ingredients. For centuries, wild mushrooms (setas) have been foraged in the forests and mountains of Spain, particularly in regions like Castilla y León, La Rioja, and Asturias, where mushroom hunting (micología) is part of the local culture.
The dish itself follows the humble “al ajillo” style of cooking, which means sautéing an ingredient in olive oil with plenty of garlic and often a hint of chili or paprika. This technique is used widely in Spanish cuisine — from shrimp (gambas al ajillo) to chicken (pollo al ajillo) — and highlights the natural flavor of the main ingredient without overpowering it.
Today, setas al ajillo remains a staple of tapas bars and home kitchens, often served alongside rustic bread or as part of a larger tapas spread. What makes it so beloved is its versatility: it’s hearty enough to stand on its own, but light enough to share as a small bite with friends, always paired with a glass of Spanish wine or cider.
Why This Dish Works
- Umami-rich and meaty texture — oyster mushrooms feel substantial and satisfying.
- Two-in-one sensation — silky garlic butter mushrooms both atop warm chickpea stewed in tomato and neatly tucked into toasty sourdough squares.
- Quick, comforting, and super sharable — perfect for weeknight cooking or dinner parties.
Garlic Butter Oyster Mushrooms with Two Serving Styles
Ingredients (Serves ~4 tapas portions)
- 400 g oyster mushrooms, torn into strips
- 3 tbsp olive oil
- 2 tbsp butter
- 4 garlic cloves, thinly sliced
- ½ tsp smoked paprika (pimentón de la Vera)
- Salt & freshly ground black pepper
- 2 tbsp chopped fresh parsley
- Optional: a squeeze of lemon
For the Chickpea Tomato Base:
- 1 cup cooked chickpeas (or canned, drained and rinsed)
- 1 cup tomato sauce (homemade or good-quality jar)
For Toasts:
- Sourdough bread, cut into thick slices and toasted
Directions
1️⃣ Sear the Mushrooms
- Heat 1 tbsp olive oil in a skillet over medium-high heat. Add oyster mushrooms in a single layer and leave them undisturbed for 3–4 minutes to develop a golden crust.
- Flip and cook another 3 minutes. Transfer to a bowl and set aside.
2️⃣ Garlic Butter Magic
- In the same pan, melt olive oil with butter. Add garlic and cook until fragrant (just under a minute).
- Stir in smoked paprika, then return mushrooms to the pan. Season with salt and pepper. Cook for 2 minutes more to meld flavors.
3️⃣ Prepare the Bases
- Warm the chickpea tomato mixture in a small saucepan or microwave.
- Toast sourdough until golden and crisp.
4️⃣ Assemble & Garnish
- For tapas: Spoon chickpeas onto plates, top with mushrooms, and finish with parsley (plus squeeze of lemon if you like).
- For toasts: Layer mushrooms over the toast, garnish with parsley, and enjoy!
Serving Suggestions
- As tapas: Serve on plates or small boards with toothpicks for dipping.
- As a main-course side: Bulk it up with a simple green salad or roasted baby potatoes.
- With wine: Savor with a crisp white or Spanish red (like Verdejo or Tempranillo).
A Memorable Meal & a Place to Visit
L’Angleiru isn’t just another restaurant—it’s a hidden Asturian treasure where the mountain air, welcoming ambiance, and mountain-view terrace all enhance platefuls of perfectly grilled mushrooms. It’s the kind of place you stumble upon and remember long after the bite.
This dish is my take on that memory, reimagined in my kitchen with British oyster mushrooms—but with the same spirit. Give it a try, and see what a little garlic butter and nostalgia can do.
