Crispy Panko & Miso Brown Butter Mushroom Pasta
Roasting the mushrooms and toasting panko on one sheet pan builds deep, toasty flavor while a silky miso brown-butter sauce turns spaghetti into something memorable on a weeknight.
This recipe answers the common craving for pasta that feels special but doesn’t require a lot of fuss. Roasting cremini and shiitake concentrates their earthy, caramelized notes while the panko browns into crunchy, toasty contrast; the sheet pan does the heavy lifting so you can focus on the finishing touches. The mushrooms come out deeply browned and slightly crisp at the edges—exactly the kind of texture that elevates a simple bowl of spaghetti.
The sauce is the quiet hero: browned butter for that warm, nutty backbone, whisked with white miso for a clean, savory lift that clings to every strand. Finish with lemon to cut through the richness, plenty of grated Parmesan for salty depth, and parsley for a green, herbaceous pop. Toss the hot pasta with reserved cooking water to make a glossy emulsion—the starch in the water is the trick that keeps the sauce silky and evenly coated.
Little practical moves make this recipe work every time: scatter the panko in one corner of the pan and give the mushroom side a single toss halfway through baking so the crumbs toast without burning. Cook the spaghetti just shy of al dente and save 1–1½ cups of the pasta water to loosen the sauce. If you want to prep ahead, roast the mushrooms and panko earlier in the day and reheat the pan briefly in a hot oven so the crumbs stay crisp—then finish the miso brown butter and toss everything together at the last minute.
Serve it piping hot with extra Parmesan and a squeeze of lemon at the table. The result is an umami-forward, texturally interesting pasta that feels both indulgent and effortless—perfect for a cozy weeknight or a low-key dinner where you want something a little elevated without complicated steps.
Ingredients
How to Make Sheet-Pan Miso Brown Butter Mushroom Pasta
- Preheat the oven to 425°F (220°C) and line a large rimmed sheet pan with foil or parchment.
- Trim and slice the mushrooms into 1/4–1/2-inch pieces; thinly slice the shallot and mince the garlic. Toss mushrooms, shallot, and garlic on the sheet pan with 2 tbsp olive oil, 1/2 tsp kosher salt (from the measured amount), and 1/4 tsp black pepper so everything is in a single layer.
- Scatter the panko in one corner of the sheet pan and drizzle it with 1 tbsp melted butter (reserve the remaining butter for the sauce); roast the pan for 18–22 minutes until mushrooms are deeply browned and panko is crisp and golden, tossing the mushroom side once halfway through.
- Meanwhile, bring a large pot of water to a boil, salt it with the remaining kosher salt, and cook the spaghetti until just shy of al dente per package directions; reserve 1 to 1 1/2 cups of pasta cooking water, then drain the pasta.
- In a large skillet over medium heat, melt the remaining 3 tbsp butter and cook, swirling the pan, until it foams and turns nutty brown with a toasted aroma (about 3–4 minutes); watch closely so it doesn’t burn.
- Remove the skillet from the heat and whisk in the white miso paste until smooth, then add 1 tbsp lemon juice, a pinch of red pepper flakes, and 1/2 cup reserved pasta water to loosen into a silky sauce; return to very low heat only to keep warm.
- Add the drained spaghetti to the skillet and toss vigorously to coat, adding up to 1/2 cup more pasta water as needed to reach a glossy, clingy sauce consistency.
- Fold in the roasted mushrooms and most of the toasted panko (reserve a little for garnish), then stir in the grated Parmesan and chopped parsley; taste and adjust seasoning with black pepper and a little salt only if needed.
- Serve immediately with extra Parmesan, the reserved crunchy panko on top, a lemon wedge on the side, and an extra pinch of red pepper flakes if desired.
