Ingredients at a Glance

This recipe uses simple, accessible ingredients. Each component plays a key role in balancing flavor and texture.

  • Chicken breasts: Boneless, skinless; can be substituted with thighs for juiciness.
  • Broccolini: A slender, slightly sweeter cousin to broccoli; can be swapped for regular broccoli, asparagus, or green beans.
  • Olive oil & butter: Used for sautéing, creating a base for fond development and flavor.
  • Shallot or onion: Lends gentle sweetness to the sauce; can use yellow onion in a pinch.
  • Heavy cream: Rich, luxurious mouthfeel—half-and-half may be used for a lighter sauce.
  • Dijon & whole grain mustard: The dual-mustard approach creates layers of pungency, heat, and texture in the sauce.
  • White wine (optional): Adds brightness and complexity; sub chicken broth if preferred.
  • Garlic: Aromatic depth, ties flavors together.
  • Salt & pepper: Seasoning for chicken and sauce balance.
  • Lemon zest (garnish, optional): A bright finish to cut the richness.

Step-by-Step Cooking Instructions

Follow this straightforward preparation for flawless results every time. See below for practical tips and kitchen wisdom at each step.

  1. Prep and season:
    • Pat chicken breasts dry. Season both sides liberally with kosher salt and cracked black pepper.
    • Trim broccolini, slicing any thick stems lengthwise for even cooking.
  2. Brown the chicken:
    • Heat olive oil and butter in a large skillet over medium-high heat.
    • Sear chicken until golden brown on both sides (about 4–5 minutes per side). Remove to a plate when just cooked through.

    Tip: Don’t overcrowd the skillet; work in batches if needed so the chicken browns—not steams.

  3. Sauté aromatics & deglaze:
    • Lower the heat to medium. Add shallots and a pinch of salt; sauté until translucent (about 2–3 minutes).
    • Stir in minced garlic, cooking for 30 seconds until fragrant.
    • Pour in white wine or chicken broth and scrape the browned bits from the pan (this is crucial for the sauce’s depth).
  4. Blanch broccolini:
    • While aromatics cook, bring a medium pot of salted water to a boil.
    • Add broccolini and cook for 2–3 minutes, just until bright green and crisp-tender.
    • Drain and set aside. You can season lightly with salt and a drizzle of olive oil.
  5. Make mustard cream sauce:
    • Pour heavy cream into the skillet with aromatics and wine.
    • Whisk in both mustards, stirring until combined. Bring to a simmer and cook for 2–3 minutes, letting the sauce thicken slightly.
    • Taste and adjust seasoning with salt and pepper.
  6. Finish and assemble:
    • Return the chicken to the skillet, nestling in the sauce until warmed through, about 2 minutes.
    • Arrange blanched broccolini around the chicken or serve on the side. Spoon sauce on top and garnish with optional lemon zest.

Serving Suggestions

  • With grains or starch: Serve chicken and broccolini over garlic mashed potatoes, buttered egg noodles, or fluffy steamed rice to soak up the sauce.
  • For extra fiber: Pair with cooked farro, quinoa, or wild rice pilaf.
  • Wine pairing: A crisp Sauvignon Blanc or lightly oaked Chardonnay highlight the mustard’s tang.

Storage and Make-Ahead Tips

  • Refrigerate: Store leftovers in an airtight container for up to 3 days; keep sauce separate if possible to preserve broccolini’s texture.
  • Reheat: Warm gently over low heat to avoid breaking the sauce.
  • Not freezer-friendly: Cream-based sauces tend to separate after freezing and thawing.

Expert Tips & Variations

  • Pound chicken breasts: For quick, even cooking, pound to uniform thickness.
  • Add herbs: A sprinkle of fresh tarragon, chives, or parsley brightens the finished dish.
  • Make it spicy: Stir in crushed pepper flakes or a teaspoon of horseradish to the sauce for heat.
  • Gluten-free option: Ensure your mustards and chicken broth (if using) are gluten-free.
  • Vegetarian twist: Swap chicken for thick slices of roasted cauliflower or seared tofu, and use vegetable broth in place of wine or chicken broth.

Frequently Asked Questions (FAQs)

Can I substitute broccolini with another vegetable?

Absolutely. Broccoli, asparagus, or even green beans work well; just adjust the blanching time to reach the right crisp-tender texture.

Is the mustard cream sauce spicy?

No—while Dijon and whole-grain mustards add tang and subtle heat, the heavy cream softens their pungency, creating a balanced, mild sauce.

Can I prepare this recipe ahead?

You can make the chicken and sauce a day in advance; keep them refrigerated and reheat gently before serving. Blanch broccolini just before serving for optimal color and crunch.

How do I prevent the sauce from breaking?

Simmer the sauce gently and avoid boiling after adding cream. If the sauce splits, quickly whisk in a splash of warm water to bring it back together.

Is the recipe keto-friendly?

Yes; it’s naturally low in carbohydrates with a high-protein, high-fat profile that fits well in many keto meal plans.
