Alex Raij’s Mushroom Confit (Setas Confitadas): A Basque Approach to Slow-Cooked Mushrooms
Unlocking Basque flavors and a hands-off, crowd-pleasing method for silky confit mushrooms and fragrant infused oils.
Alex Raij’s Mushroom Confit (Setas Confitadas): The Art of Oil-Poached Mushrooms
If classic sautéed mushrooms fill your kitchen with sizzle and demand constant attention, Alex Raij’s Basque-inspired mushroom confit offers a calm, hands-off alternative. This method trades the urgency of browning for gentle, slow flavor infusion, yielding mushrooms that are tender, remarkably moist, and dripping with umami. Even better, the resulting mushroom- and garlic-scented oil becomes a culinary treasure in its own right, ready to elevate countless future dishes.
Why Try Mushroom Confit Instead of Sautéed Mushrooms?
- Cook in bulk: Unlike traditional browning methods, you can easily scale this recipe up or down depending on the amount of mushrooms you have without overcrowding the pan.
- Mild, controlled heat: Slow oil-poaching at low temperatures preserves moisture and enhances the pure flavor of the mushrooms.
- Minimal active time: Let the mushrooms gently simmer while you tend to other kitchen tasks—no constant stirring or heat management required.
- Versatile leftovers: Not just the mushrooms but also the infused oil are perfect bases for riffs in later recipes, from fried eggs to vinaigrettes and sautéed greens.
The Basque Inspiration: Setas Confitadas
Setas confitadas, as presented by chef Alex Raij, draws upon the Basque region’s deep appreciation for both humble ingredients and culinary restraint. The technique involves submerging mushrooms in olive oil, slowly infusing them (and the oil) with garlic and salt, and letting the natural flavors bloom over gentle heat. This method is ideal for days when cooking is as much about patience and quiet as it is about results—think more gentle simmer than high-octane sear.
How Confit Differs from Other Cooking Methods
- Confit: Ingredients are slowly cooked at low temperature, fully submerged in oil or fat. Temperatures stay low (typically at or below 300°F), leading to tender textures and long shelf life.
- Sauté: Quick-cooking in a small amount of fat at high heat. Ideal for browning but impractical for large volumes of delicate ingredients without crowding the pan.
- Deep-fry: Faster and hotter than confiting, which emphasizes crispness not preservation or subtlety.
What Mushrooms Work Best?
While Alex Raij favors oyster mushrooms, the technique works for nearly any variety:
- Button mushrooms (white or brown cremini)
- Porcini (fresh or rehydrated)
- Chanterelles, hedgehog, milk cap, or St. George’s mushrooms
- Wild mushrooms for earthier, more complex flavors
Remember: all mushrooms shrink during cooking, so it’s wise to use more than you might expect—the pan will look full, but the yield condenses into concentrated flavor.
Ingredients List
- 4 pounds mushrooms, trimmed (use any mix—oyster, button, wild, etc.)
- Extra-virgin olive oil (enough to cover the mushrooms)
- Kosher salt
- 6 cloves garlic
- 4 to 6 thick slices country bread
- Juice of 1 lemon
- Chopped fresh flat-leaf parsley (for garnish)
Step-by-Step Directions: How to Make Mushroom Confit
- Step 1: Mushroom Poaching
Place the trimmed mushrooms in a large saucepan and add enough olive oil to just cover them. The mushrooms will float, which is fine. Season with salt. Smash 1 garlic clove with the flat of a knife and add to the pan. Gently heat the oil over medium-low until you see light simmering—not rapid bubbling. Reduce the heat to low so the mushrooms percolate quietly in the oil. Cook gently for 20 minutes or more (time depends on mushroom size), until the mushrooms are silken, tender, and deeply seasoned.
Remove from heat and allow the mixture to cool. As it rests, the juices will separate from the oil. Pour off the oil (save it!) and mushroom juices (reserve these, too). Discard the garlic clove. Return the mushrooms to their infused oil for storage until you’re ready to serve.
- Step 2: Toast the Bread
Preheat the oven to 350°F (175°C). Rub both sides of each country bread slice with a garlic clove. Arrange bread on a baking sheet, drizzle with a bit of the mushroom oil, and toast for about 6 minutes, until golden and crisp.
- Step 3: Make Garlic Chips
Line a plate with paper towels. Thinly slice the remaining garlic cloves. In a small saucepan, combine the slices with half a cup of reserved mushroom oil and cook over medium heat for about 35 seconds—or until golden brown, aromatic, and just crisping. Use a slotted spoon to transfer the chips to your prepared plate to drain.
- Step 4: Assemble and Serve
Gently reheat the mushrooms in their oil. Also, heat the reserved mushroom juices separately. Drain the warmed mushrooms, slice to bite-sized pieces if needed, and toss with fresh lemon juice. Add one slice of toast to each bowl, top with mushrooms, then spoon over some warm mushroom juices.
Finish with a drizzle of garlic-infused oil, a handful of garlic chips, and chopped fresh parsley. Serve immediately for ultimate flavor and texture.
- Step 5: Storing the Confit
The mushrooms, kept fully submerged in oil, will keep in the refrigerator for up to four days. Both the mushrooms and their oil can be used as flavor boosters in numerous dishes.
Tips, Variations, and Serving Ideas
- Upgrade simple fare: Use the confit and its oil to top grains, beans, or cooked vegetables.
- Make luxe croutons: Cube stale bread, toss with the mushroom oil, bake until crisp, and use as toppers for soup or salad.
- Infuse sauces: Add the oil to vinaigrettes, dips, or cream sauces for an unmistakable umami lift.
- Pair with proteins: Mushrooms confit complement eggs, grilled poultry, roasted meats, or as a filling for savory tarts.
- Season to your taste: Finish with a sprinkle of flaky salt, a splash of vinegar, or sherry for brightness.

Frequently Asked Questions (FAQs)
Q: Can I use other oils besides extra-virgin olive oil?
A: For the richest flavor and most authentic Basque result, extra-virgin olive oil is recommended. You could substitute another neutral oil in a pinch, but you’ll lose some depth and aroma.
Q: Do I need to wash the mushrooms before confiting?
A: It’s best to brush or wipe mushrooms clean with a damp cloth to avoid excess water, which can dilute the flavor. Only rinse if absolutely necessary, and dry thoroughly before cooking.
Q: Will the mushrooms be greasy?
A: No. Though cooked in oil, confited mushrooms absorb flavor and some fat, but excess oil is drained off. The resulting mushrooms are moist yet not soggy or heavy.
Q: How do I store leftover mushroom confit?
A: Ensure the mushrooms are fully covered with oil in an airtight container; they’ll keep for up to 4 days in the refrigerator. Use clean utensils to avoid contamination. The flavored oil can also be strained and stored for culinary use.
Q: Can I freeze mushroom confit?
A: While possible, freezing may alter texture. The mushrooms are best enjoyed fresh or within a few days of preparation.
