Why You Will Love This Recipe

This 5-Ingredient Savory Miso Butter Pasta comes together faster than takeout and requires almost no cleanup. The combination of butter, garlic, and white miso creates a deeply savory sauce without heavy cream. It is versatile, vegetarian-friendly, and uses ingredients you likely already have in your kitchen.

Ingredients

• 8 oz spaghetti or linguine
• 3 tablespoons unsalted butter
• 2 tablespoons white miso paste
• 2 cloves garlic, minced
• 1/4 cup grated Parmesan cheese

Step-by-Step Instructions

1. Bring a large pot of salted water to a boil. Cook the pasta according to package directions until al dente. Reserve about 1/2 cup of pasta water, then drain the pasta.
2. While the pasta cooks, melt the butter in a large skillet over medium heat.
3. Add the minced garlic to the skillet and sauté for about 1 minute, just until fragrant. Do not let it brown.
4. Stir in the white miso paste until smooth. Add a splash of the reserved pasta water to loosen the mixture into a sauce.
5. Add the cooked pasta to the skillet and toss to coat. Gradually add more pasta water as needed to create a silky consistency.
6. Remove the skillet from the heat and stir in the grated Parmesan cheese until melted and creamy.
7. Serve immediately with optional garnishes such as black pepper or chopped parsley.

Expert Tips / Pro Tips

• Do not boil the miso paste aggressively. High heat can diminish its delicate fermented flavor.
• Reserve starchy pasta water before draining. It is the secret to emulsifying the butter and miso into a smooth sauce.
• Use freshly grated Parmesan for the best melt and flavor. Pre-grated cheese often contains anti-caking agents that can make the sauce grainy.
• Toss the pasta off the burner when adding the cheese to help prevent the sauce from separating.
• Taste before adding extra salt. Miso paste is already salty, so you may not need any additional salt at all.

Variations & Substitutions

• Pasta: Try fettuccine, bucatini, or gluten-free pasta if needed.
• Miso: White miso is mild and sweet. Yellow miso works well, while red miso is stronger and saltier—use less if substituting.
• Cheese: Swap Parmesan for Pecorino Romano or nutritional yeast for a dairy-free option.
• Garlic: Use garlic powder in a pinch, but fresh garlic provides the best aroma.
• Add-ins: Stir in sautéed mushrooms, baby spinach, peas, grilled chicken, or shrimp for extra protein and vegetables.

Serving Suggestions

Serve this 5-Ingredient Savory Miso Butter Pasta in shallow bowls garnished with freshly cracked black pepper, chopped fresh parsley, or extra grated Parmesan. A squeeze of lemon juice at the end brightens the rich, savory flavor. Pair it with a simple green salad, roasted broccoli, or crusty garlic bread for a complete meal.

Storage, Freezing & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Freezing is not highly recommended because the butter and miso sauce can separate upon thawing, but you can freeze it for up to 1 month if needed. Thaw overnight in the refrigerator before reheating.

To reheat, warm the pasta gently in a skillet over low heat with a splash of water or milk to loosen the sauce. You can also microwave it in 30-second intervals, stirring between each interval until heated through.
