Bringing restaurant-quality flavor to your home kitchen is simple with this colorful stir-fry. Thick, chewy udon noodles mingle with plump bay scallops, crisp bacon, and delicate baby bok choy, all united by a tangy citrus-soy sauce. This dish balances salty, sweet, and umami with a quick preparation—making it perfect for busy weeknights.

Why This Recipe Works

  • Hearty udon noodles soak up the savory sauce for maximum flavor.
  • Bay scallops cook quickly and stay perfectly tender, adding sweet ocean notes.
  • Bacon provides smoky richness, contrasting beautifully with bright, juicy citrus.
  • Baby bok choy brings freshness and a slight crunch for textural contrast.
  • An all-in-one sauce—with soy, citrus, honey, and a hint of spice—glazes the entire dish.

Ingredients

  • 6 ounces smoked bacon, diced
  • 8 ounces fresh or frozen udon noodles
  • 8 ounces bay scallops, patted dry
  • 2 small heads baby bok choy, rinsed, ends trimmed, stems and leaves separated
  • 1/4 cup tamari or regular soy sauce
  • 2 tablespoons rice vinegar
  • Juice of 1 orange
  • Juice of 1 lime
  • 1 1/2 tablespoons honey
  • 1/4 teaspoon red pepper flakes, or more to taste
  • 1 tablespoon neutral oil (plus more as needed)
  • 2 tablespoons chopped cilantro (plus extra for garnish)
  • 2 tablespoons toasted peanuts, roughly chopped (for garnish, optional)
  • Kosher salt and freshly ground black pepper, to taste

Step-by-Step Instructions

1. Prepare Ingredients

  • Dice bacon while it’s still cold for easy cutting.
  • Rinse and trim baby bok choy; separate stems from leaves for even cooking.
  • Pat scallops dry to encourage caramelization.
  • Cook or thaw udon noodles according to package instructions, then drain and rinse under cold water.

2. Render Bacon

Place the diced bacon in a large skillet or wok over low heat. Allow the fat to render slowly for crispy yet tender bacon bits—this takes 6-8 minutes. Stir occasionally, watching closely to avoid scorching.

3. Mix the Citrus-Soy Sauce

  • In a small bowl, combine soy sauce, rice vinegar, orange juice, lime juice, honey, and red pepper flakes. Whisk thoroughly.
  • Tip: Coat your measuring spoon with a drop of oil before measuring honey—it will pour easily.

4. Sauté Bok Choy

Use a slotted spoon to transfer crisp bacon from the skillet to a paper towel-lined plate. Reserve 1 tablespoon bacon fat in the pan (add neutral oil if needed).

  • Add the bok choy stems and stir-fry over medium-high heat for 1-2 minutes. When they begin to soften, add the leafy tops and cook briefly until just wilted.

5. Cook the Bay Scallops

Push bok choy to one side. Increase heat to high, and add bay scallops in a single layer. Cook for 1-2 minutes, flipping halfway, until just firm and opaque. Season lightly with salt; do not overcook.

6. Combine Everything

  • Add cooked udon noodles directly to the pan.
  • Pour in the prepared citrus-soy sauce, tossing everything to coat the noodles thoroughly. The sauce should bubble slightly and glaze the noodles, scallops, and bok choy.
  • Return bacon to the pan, stirring gently to distribute.
  • Add cilantro and toss to combine.

7. Finish and Garnish

  • Portion noodles and toppings into individual bowls.
  • Scatter toasted peanuts and extra chopped cilantro over each bowl for crunch and brightness.
  • Serve immediately and enjoy while hot.

Recipe Tips and Variations

  • If you can’t find fresh udon noodles, use vacuum-sealed or frozen; dried udon will also work with adjusted cooking times.
  • Try substituting shrimp or sea scallops (halved) if bay scallops are unavailable.
  • For a vegetarian version, omit bacon and use shiitake mushrooms; boost umami with a splash of mushroom soy sauce.
  • Swap baby spinach or napa cabbage for bok choy if desired.
  • Increase red pepper flakes for more heat, or add a drizzle of chili oil just before serving.

  • Finishing with fresh herbs and nuts lends brightness and a satisfying crunch.

Serving Suggestions

  • Serve alongside a simple side of pickled cucumber or edamame for added freshness.

Frequently Asked Questions (FAQs)

Can I use frozen scallops for this recipe?

Yes. Thaw scallops thoroughly in the refrigerator, then pat dry to remove excess moisture before cooking. This helps them sear without steaming.

What’s the best substitute for udon noodles?

If you can’t find udon, thick wheat noodles, soba, or even Italian pasta like linguine can stand-in, though texture will vary slightly.

Can I make this recipe in advance?

This dish is best enjoyed immediately to maintain the scallops’ tenderness and the noodles’ chewy texture. If needed, reheat gently in a skillet and add a splash of water to loosen the sauce.

How spicy is this dish?

It features a mild heat from red pepper flakes. Adjust the amount to your preference, or omit entirely for a mild version.

Are there gluten-free options?

Use gluten-free tamari and check noodle labels, as some brands offer gluten-free udon or rice noodles that work well with the recipe.

Storing Leftovers

  • Cool leftovers promptly and refrigerate in an airtight container for up to 2 days.
  • To reheat, warm in a skillet over medium heat with a splash of water or stock, stirring gently until hot.
  • Scallops may become firmer upon reheating but will remain flavorful.

Chef’s Notes and Tricks

  • Use freshly squeezed citrus juice for optimal brightness and flavor in the sauce.
  • Don’t crowd the pan when cooking scallops—work in batches if necessary for even searing.
  • Keep everything prepped and ready before you start stir-frying; this dish comes together quickly once you begin cooking.
