In a large bowl, toss:\n    -   Cut mushrooms\n    -   Onion\n    -   Olive oil\n    -   ½ teaspoon salt\n    -   ½ teaspoon black pepper\n2.  Place on a rimmed baking sheet in a single layer.\n3.  Roast for about 15 minutes, or until cooked and firm.\n4.  Remove from oven and set aside.\n\n===Bake Pie Shell==\n\n1.  Prick pie shell all over with a fork.\n2.  Prebake shell for 10 to 15 minutes, until lightly browned.\n3.  **Reduce oven temperature to 350°F.**\n\n### Combine Eggs\n\n1.  In a large bowl, whisk together:\n    -   Buttermilk\n    -   Eggs\n    -   1 tablespoon chopped fresh thyme\n    -   Salt and black pepper, to taste.\n\n### Combine Mushrooms\n\n1.

Spread mushroom mixture in the bottom of the pie shell in an even\n    layer.\n\n### Bake Quiche\n\n1.  Pour buttermilk-egg mixture over the mushroom mixture, ensuring that all\n    of the mushroom mixture is covered.\n2.  Bake for 45 to 55 minutes, or until a knife inserted into the center\n    of the quiche comes out clean.\n3.  Serve warm or at room temperature.\n\n## Notes\n\n-   **Seasoning split stated (2026-07-30):** salt and pepper were listed once\n    (½ teaspoon each) but called for twice — fully consumed tossing the\n    mushrooms, then requested again in the custard with nothing left allocated.\n    The listed ½ teaspoon of each is where the ingredient list places it, with\n    the mushrooms, so it stays there and is now named at that step; the custard\n    is seasoned to taste. No amount was invented for the custard, because the\n    recipe never states one.\n-   **Thyme placement stated (2026-07-30):** two thyme lines (1 tablespoon and\n    2 teaspoons) sat against two steps that each asked for an unqualified\n    \"Thyme\". Assigned by the ingredient list's own ordering, which follows the\n    step order — the tablespoon sits in the buttermilk/egg group and the\n    2 teaspoons sit with the gruyère. Total thyme is unchanged either way.\n-   **Stale source wording removed (2026-07-30):** the bake step said \"Pour\n    cream-egg mixture\", but there is no cream in this recipe — the headnote\n    substitutes low-fat buttermilk for the heavy cream of the original. Now\n    reads \"buttermilk-egg mixture\".\n","draft":false,"servings":"6","prep_time":"20 minutes","cook_time":"1 hour 10 minutes","total_time":"1 hour 30 minutes","source_name":"Whole Foods Market","source_url":"http://www.wholefoodsmarket.com/recipe/mushroom-and-gruy%C3%A8re-quiche","created_at":"2014-12-01T04:36:37Z","updated_at":"2026-08-27T21:27:24.733978Z","categories":["Main"],"tags":["Cheese","Gruyère","Mushrooms"],"methods":["Baked"],"ingredients":[{"section":"","items":["-   113g (¼ lb) cremini mushrooms, cut into quarters or eighths, depending","-   113g (¼ lb) portobello mushroom caps, diced","-   113g (¼ lb) shiitake mushrooms, stems removed and discarded, cut into","-   ½ medium yellow onion, thinly sliced","-   1 tablespoon extra-virgin olive oil","-   ½ teaspoon salt, for the mushrooms","-   ½ teaspoon black pepper, for the mushrooms","-   Salt and black pepper, to taste, for the custard","-   120ml (½ cup) low-fat buttermilk","-   2 eggs","-   1 tablespoon chopped fresh thyme, for the custard","-   112g (4oz) gruyère cheese, shredded (about 1 ½ cups)","-   2 teaspoons chopped fresh thyme, for the mushroom and cheese mixture"],"parsed":[{"raw":"-   113g (¼ lb) cremini mushrooms, cut into quarters or eighths, depending","qty":113,"unit":"g","item":"cremini mushrooms","prep":"cut into quarters or eighths, depending"},{"raw":"-   113g (¼ lb) portobello mushroom caps, diced","qty":113,"unit":"g","item":"portobello mushroom caps","prep":"diced"},{"raw":"-   113g (¼ lb) shiitake mushrooms, stems removed and discarded, cut into","qty":113,"unit":"g","item":"shiitake mushrooms, stems removed and discarded, cut into"},{"raw":"-   ½ medium yellow onion, thinly sliced","qty":0.5,"item":"medium yellow onion","prep":"thinly sliced"},{"raw":"-   1 tablespoon extra-virgin olive oil","qty":1,"unit":"tbsp","item":"extra-virgin olive oil"},{"raw":"-   ½ teaspoon salt, for the mushrooms","qty":0.5,"unit":"tsp","item":"salt","prep":"for the mushrooms"},{"raw":"-   ½ teaspoon black pepper, for the mushrooms","qty":0.5,"unit":"tsp","item":"black pepper","prep":"for the mushrooms"},{"raw":"-   Salt and black pepper, to taste, for the custard","item":"Salt and black pepper, to taste, for the custard"},{"raw":"-   120ml (½ cup) low-fat buttermilk","qty":120,"unit":"ml","item":"low-fat buttermilk"},{"raw":"-   2 eggs","qty":2,"item":"eggs"},{"raw":"-   1 tablespoon chopped fresh thyme, for the custard","qty":1,"unit":"tbsp","item":"chopped fresh thyme","prep":"for the custard"},{"raw":"-   112g (4oz) gruyère cheese, shredded (about 1 ½ cups)","qty":112,"unit":"g","item":"gruyère cheese","prep":"shredded"},{"raw":"-   2 teaspoons chopped fresh thyme, for the mushroom and cheese mixture","qty":2,"unit":"tsp","item":"chopped fresh thyme","prep":"for the mushroom and cheese mixture"}]}],"related":[{"slug":"pate-brisee","title":"Pâte Brisée","relation":"component"}],"servings_int":6,"qc":{"status":"passed","last_checked_at":"2026-08-27T21:28:37.708504Z","checked_by":"robert@sigler.io","standard_version":"2026-07-30","findings_count":0,"stale":false}}
