Why You’ll Love Brown Butter Miso & Roasted Garlic Radiatori with Crispy Shallots Recipe

I love how this recipe transforms a few simple ingredients into a restaurant-worthy pasta dish with layers of flavor. The combination of brown butter and miso creates a silky sauce that tastes rich and complex without requiring heavy cream.

The roasted garlic gives the pasta a mellow sweetness that balances the savory elements perfectly. I also enjoy how the crispy shallots add texture and contrast to the creamy sauce.

Another reason I keep making this recipe is how cozy and satisfying it feels while still being easy enough for a weeknight dinner. The radiatori shape catches all the sauce beautifully, making every bite flavorful.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

12 ounces (340 grams) radiatori pasta
6 tablespoons (85 grams) unsalted butter
2 tablespoons (30 grams) white miso paste
2 whole garlic bulbs
2 medium shallots, thinly sliced
3 tablespoons olive oil, divided
1 cup (90 grams) grated parmesan cheese
1 teaspoon fresh thyme leaves, chopped
1 teaspoon salt, or to taste
1/2 teaspoon freshly ground black pepper

Directions

1. I preheat the oven to 400°F (200°C). I slice the tops off the garlic bulbs, drizzle them with 1 tablespoon olive oil, wrap them in foil, and roast for 35 to 40 minutes until soft and caramelized.
2. While the garlic roasts, I bring a large pot of salted water to a boil and cook the radiatori pasta according to package instructions until al dente. Before draining, I reserve 1/2 cup of pasta water.
3. In a large skillet over medium heat, I melt the butter and cook it slowly until it turns golden brown and develops a nutty aroma. I stir frequently to prevent burning.
4. I whisk the white miso paste into the browned butter until smooth and fully combined.
5. Once the garlic is roasted, I squeeze the softened cloves from their skins directly into the skillet and mash them gently into the sauce.
6. I add the cooked pasta to the skillet and toss everything together until coated. I gradually pour in reserved pasta water as needed until the sauce becomes silky and clings to the pasta.
7. I stir in the grated parmesan cheese, chopped thyme, salt, and freshly ground black pepper. I taste and adjust the seasoning if needed.
8. In a separate pan, I heat the remaining 2 tablespoons olive oil over medium heat and fry the sliced shallots in batches until golden and crispy. I transfer them to paper towels to drain.
9. I top the pasta with the crispy shallots and serve immediately while warm.

Variations

I sometimes use spaghetti, rigatoni, or fusilli when I do not have radiatori on hand. Any pasta shape that holds sauce well works beautifully.

For extra greens, I like stirring in baby spinach or sautéed kale just before serving.

When I want a little heat, I add crushed red pepper flakes to the brown butter sauce.

I occasionally swap parmesan with pecorino romano for a sharper, saltier flavor profile.

For added protein, I enjoy serving this pasta with roasted mushrooms or crispy tofu.

Storage/Reheating

I store leftover pasta in an airtight container in the refrigerator for up to 3 days.

To reheat, I warm the pasta gently in a skillet over low heat with a splash of water or broth to loosen the sauce. I avoid overheating because the parmesan sauce can become too thick.

I prefer making fresh crispy shallots for serving since stored shallots lose their crunch over time.

FAQs

What does white miso add to the pasta?

White miso adds a savory umami flavor that deepens the sauce and balances the richness of the butter.

Can I make this recipe ahead of time?

I can roast the garlic and fry the shallots ahead of time, but I prefer combining the pasta and sauce fresh before serving.

What is the best substitute for radiatori pasta?

I like using fusilli, cavatappi, rigatoni, or penne because they hold the sauce well.

How do I know when the butter is browned properly?

I watch for a golden brown color and a nutty aroma. Small brown bits will form at the bottom of the pan.

Can I use red miso instead of white miso?

I can, but red miso has a much stronger and saltier flavor, so I use a smaller amount.

Why should I reserve pasta water?

The starchy pasta water helps emulsify the sauce and creates a silky texture that coats the pasta evenly.

Can I make this dish vegetarian?

Yes, the recipe is already vegetarian as written.

How do I keep shallots crispy?

I fry them until deeply golden and add them just before serving to maintain their crunch.

Can I freeze the leftovers?

I do not recommend freezing this pasta because the sauce texture can change after thawing.

What can I serve with this pasta?

I like serving it with a crisp green salad, roasted vegetables, or warm crusty bread.
