Steps
Before you start
- Pat mushrooms dry with paper towels so they brown properly and don't steam
- Slice sourdough bread and have it ready for toasting
- Measure out cream and white wine ahead of time
Toast bread cubesOven 375°F / 190°C
- Preheat your oven to 375°F (190°C).
- Toss the sourdough bread cubes with 1 tablespoon of the olive oil and a small pinch of salt on a sheet pan.
- Spread in a single layer and toast for 8–10 minutes, stirring halfway through, until the edges are golden and crispy but the insides stay slightly chewy.
- Set aside.

Ready when: Edges are golden brown, bread is fragrant
Tip: Don't walk away—bread can burn quickly. Stir halfway to ensure even browning.
Sear mushrooms in batches
- While bread toasts, heat the Dutch oven over medium-high heat.
- Add 1 tablespoon of butter and let it foam.
- Working in two batches so mushrooms aren't crowded, add half the mushroom pieces and cook undisturbed for 3–4 minutes until their bottoms are deeply browned.
- Stir and cook another 2–3 minutes until all sides have color.
- Transfer to a bowl.
- Repeat with remaining mushrooms and another tablespoon of butter.
- Don't skip this browning step—it builds the flavor foundation.

Ready when: Mushroom pieces are deeply browned on all sides and have released their moisture
Tip: Crowding the pan steams the mushrooms instead of browning them. Two batches means better flavor.
Soften aromatics
- Reduce heat to medium.
- Add the final tablespoon of butter to the pot.
- Once foaming, add the sliced shallots and a pinch of salt.
- Cook, stirring often, for 4–5 minutes until the shallots are softened and just starting to turn golden at the edges.
- Add the minced garlic and cook for another minute until fragrant.

Ready when: Shallots are soft and translucent with light golden edges; garlic is fragrant
Tip: Lower the heat after searing to avoid burning the garlic. Burnt garlic tastes bitter.
Deglaze and reduce wine
- Pour in the white wine, stirring to scrape up any browned bits stuck to the bottom of the pot (this fond is flavor gold).
- Bring to a simmer and let it bubble gently for 3–4 minutes, reducing the wine by about half so the harsh alcohol flavor mellows and the sauce becomes more concentrated.

Ready when: Wine is noticeably reduced to about ½ cup; no raw alcohol smell
Tip: Keep the heat moderate so the wine reduces gently rather than boiling away too fast.
Add mushrooms and aromatics
- Return the seared mushrooms and any juices they released back to the pot.
- Stir in the Dijon mustard until well combined.
- Add the fresh thyme sprigs and bay leaf, then pour in the cream.
- Stir everything together gently.

Ready when: Cream is incorporated and the mixture is evenly combined
Tip: Stir gently to avoid breaking up the mushroom pieces too much.
Simmer braise gently
- Bring the braise just to a gentle simmer over medium-low heat.
- Cover the pot with the lid and reduce heat to low.
- Simmer gently for 15–18 minutes, stirring occasionally, until the mushrooms are very tender and the sauce has thickened slightly and become silky.
- The cream may separate slightly into a glossy liquid—this is normal and desirable.

Ready when: Mushrooms are fall-apart tender; sauce coats the back of a spoon and smells deeply savory
Tip: Keep heat low to prevent the cream from curdling or boiling. A gentle simmer is all you need.
Taste and season
- Remove from heat.
- Discard the thyme sprigs and bay leaf.
- Taste the braise and season generously with kosher salt and freshly ground black pepper.
- Start with ½ teaspoon salt and ¼ teaspoon pepper, then adjust to your preference.
- The sauce should taste rich and savory with a hint of thyme undertone.

Ready when: Seasoning is balanced; flavors are vibrant and well-rounded
Tip: Season at the end so you can taste as you go. It's easier to add salt than remove it.
Serve with bread dunkers
- Ladle the creamy mushroom braise into shallow bowls or wide, shallow dishes.
- Top with a generous handful of the toasted sourdough croutons.
- Drizzle a little extra-virgin olive oil over the top and scatter with fresh parsley if using.
- Serve immediately while the braise is hot and the bread cubes still have some crisp.

Ready when: Bread is at the table, braise is steaming hot
Tip: Add the bread croutons just before serving so they don't get soggy. Guests can dunk as they eat.
Good to know
Tips
- Pat your mushrooms completely dry with paper towels before searing—any moisture prevents browning and traps steam. This step takes 30 seconds and makes all the difference.
- Don't stir the mushrooms constantly while they sear. Let them sit undisturbed for 3–4 minutes so they develop a caramelized crust. Only stir when they've browned.
- The cream may look slightly separated after braising (pools of darker liquid around lighter cream)—this is the natural separation of fat and water and actually creates a silkier sauce. Stir gently before serving.
- For a vegetarian-friendly option, this braise pairs beautifully with crusty bread, a simple green salad, and a dry white wine to drink. It's elegant enough for dinner guests yet comforting enough for a weeknight meal.
Make ahead
You can braise the mushrooms up to 1 day ahead. Cool completely, cover, and refrigerate. Reheat gently in a covered pot over low heat for 10–12 minutes, stirring occasionally, until hot. Toast the bread croutons on the day of serving so they stay crispy.
Storage & reheating
Store the braise (without bread croutons) in an airtight container in the refrigerator for up to 3 days. Reheat gently over low heat on the stove. Toasted bread cubes can be stored in an airtight container at room temperature for up to 2 days; recrisp in a 300°F (150°C) oven for 3–4 minutes if needed. The braise can be frozen for up to 2 months in a freezer-safe container; thaw overnight in the fridge and reheat gently before serving.
Substitutions
- dry white wine (Sauvignon Blanc or Pinot Grigio) → dry vermouth or additional mushroom broth. Use the same amount. Vermouth adds herbal notes; broth makes the sauce earthier. Both work beautifully.
- heavy cream → crème fraîche or sour cream mixed with a splash of milk. Use the same amount. Crème fraîche won't curdle if heated too high and adds subtle tang. Sour cream is tangier; thin it slightly with milk so it pours smoothly.
- fresh thyme sprigs → 1½ teaspoons dried thyme or ½ teaspoon herbes de Provence. Dried herbs are more concentrated. Add them in step 5 with the cream rather than at the start so they don't get bitter.
- sourdough bread → rustic white bread, ciabatta, or crusty baguette. Any sturdy bread works. Cut into 1-inch cubes and toast the same way for dunking.
