Spanish Garlic Mushroom Tapas Recipe — Classic Gambas-Style Pinchos

Spanish Garlic Mushroom Tapas, known in Spain as “Champiñones al Ajillo,” are a beloved bar-style side dish served across the country. Simple to prepare and full of flavor, they make an ideal appetizer for a Tapas spread or a light starter for a special dinner. This easy recipe—one of Joanie’s favorites—uses just a few ingredients, cooks quickly, and contains only 2.6 g net carbs per serving.

Beyond serving as an appetizer or side, these garlic mushrooms are versatile: they make a savory topping for grilled steak, pair beautifully with grilled chicken, and complement pork dishes as well. For the best texture and flavor, serve them immediately after cooking. Reheated leftovers are fine, but the mushrooms lose some of their crispness and flavor when reheated. Make them, enjoy them, and make them again—this is a reliably tasty low-carb side.

If you love garlic and Spanish tapas, you may also enjoy our Gambas al Ajillo or other Spanish-style small plates. These mushrooms lean on classic Spanish flavors—garlic, smoked paprika, and good olive oil—so keep the seasonings traditional for the best result.

Ingredients

This recipe works best with small button mushrooms. Because tapas are bite-sized, use small mushrooms and cut each in half from top to bottom for a flat, searing surface. You can cook and serve these in individual terracotta cazuelas for an authentic presentation. Aim for mushrooms that retain a firm, meaty texture after cooking—slicing each mushroom once is usually sufficient.

Joanie uses plenty of garlic, avoids rosemary to keep the dish traditional, and recommends a true Spanish smoked paprika and a good Spanish extra-virgin olive oil. Like Gambas al Ajillo, these mushrooms rely on olive oil for flavor—so use one you enjoy. Serve with crusty bread to mop up the oil, or try a low-carb bread alternative if you’re keeping carbs low.

Preparation Tips

Do not rinse mushrooms under running water; they absorb moisture and become soggy. Instead, wipe them clean with a damp cloth or paper towel. Salt only at the end of cooking—salting early draws out water and prevents searing. Use mushrooms of equal size and sear them flat-side down so they develop a lightly crusted bottom. A roomy, hot skillet is essential: the mushrooms should be spaced to allow browning, cook quickly, and absorb the olive oil without turning rubbery. Avoid stirring for the first three minutes so the seared side forms a nice texture.

Key cooking notes: use a skillet large enough to avoid crowding, preheat it well, and sear the mushrooms flat side down without stirring for the first three minutes. After searing, lower the heat, add garlic and spices, then a splash of dry sherry to deglaze and build flavor. Keep some extra olive oil on hand in case the pan dries while cooking.
