Skillet-to-Oven Pork Tenderloin with Blood Orange–Shallot Pan Sauce + Crispy Fennel & Peppery Arugula

Skillet-to-Oven Pork Tenderloin with Blood Orange–Shallot Pan Sauce + Crispy Fennel & Peppery Arugula

This is my winter weeknight flex: pork tenderloin gets a hard stovetop sear, finishes in the oven, and then you build a glossy, bright blood orange–shallot pan sauce in the same skillet. I toss in quick-sautéed fennel for sweetness and crunch, then top it all with arugula so it eats light and lively—even when it’s freezing outside.

Ingredients

  • 1 to 1.25 lb pork tenderloin(trim silver skin if present)
  • 1.25 tsp kosher salt
  • 1 tsp black pepper(freshly ground)
  • 1 tsp ground coriander(optional but highly recommended for citrus-friendly warmth)
  • 2 tbsp olive oil(divided)
  • 1 fennel bulb(thinly sliced, fronds reserved)
  • 2 shallots(thinly sliced)
  • 2 cloves garlic(finely grated or minced)
  • 0.25 tsp red pepper flakes(optional)
  • 0.5 cup dry white wine(or chicken broth)
  • 2 blood oranges(zest 1; juice both (about 1/2 cup). Navel oranges work too.)
  • 1 tsp Dijon mustard(for balance and sauce body)
  • 1 tsp honey(optional; use if your oranges aren’t very sweet)
  • 2 tbsp unsalted butter(cold, for finishing the sauce)
  • 3 cups arugula(loosely packed)
  • 1 tsp sherry vinegar(or red wine vinegar; for dressing the arugula)
  • 0.5 lemon(optional squeeze at the end if you want it extra bright)
  • a few fronds fennel fronds(Optional garnish mentioned in steps)

Instructions

  1. 1

    Heat the oven to 425°F. Pat the 1 to 1.25 lb pork tenderloin dry (this is the difference between a real sear and sad steaming). Season all over with 1.25 tsp kosher salt, 1 tsp black pepper, and 1 tsp ground coriander.

    5 min

    Tip: If you have 10 extra minutes, let the seasoned pork sit uncovered on a plate while you prep. Drier surface = better browning.

  2. 2

    In a large oven-safe skillet (12-inch), heat 1 tablespoon olive oil over medium-high. Sear the tenderloin until deeply browned on all sides, turning every 1–2 minutes.

    6 min

    Tip: Don’t move it too soon—when it’s ready to flip, it releases easily.

  3. 3

    Slide the skillet into the oven and roast until the thickest part hits 140–145°F (for juicy, slightly rosy pork). Transfer pork to a plate and rest.

    10 min

    Tip: Carryover heat will take it up a few degrees. If you like it more done, pull at 150°F.

  4. 4

    Carefully pour off excess fat, leaving about 1 tablespoon in the skillet. Add remaining 1 tablespoon olive oil, then add 1 fennel bulb, trimmed and thinly sliced and a pinch of kosher salt. Cook, stirring occasionally, until edges are browned and fennel is crisp-tender.

    6 min

    Tip: You’re not trying to melt the fennel into softness—keep it snappy for that ‘bright, not heavy’ winter vibe.

  5. 5

    Add 2 shallots, thinly sliced and cook until softened, 1–2 minutes. Add 2 cloves garlic, minced and 0.25 tsp red pepper flakes and cook 30 seconds just until fragrant.

    2 min

    Tip: Garlic burns fast here—keep it moving.

  6. 6

    Deglaze with 0.5 cup dry white wine, scraping up all the browned bits. Simmer until reduced by about half. Stir in juice and zest of 2 blood oranges, 1 tsp Dijon mustard, and 1 tsp honey (if using). Simmer 2–3 minutes until slightly syrupy.

    5 min

    Tip: If it ever tastes flat, it usually needs either a pinch of salt or a tiny splash of vinegar—not more orange.

  7. 7

    Off heat, whisk in 2 tbsp unsalted butter until the sauce turns glossy. Taste and adjust salt/pepper. Add a few fronds fennel fronds if you’ve got them.

    2 min

    Tip: Butter goes in off heat so the sauce emulsifies instead of breaking.

  8. 8

    Toss 3 cups arugula with 1 tsp sherry vinegar and a pinch of salt right on your cutting board (lazy and perfect). Slice the rested pork. Spoon fennel and pan sauce onto plates, top with pork slices, then pile arugula over the top so it wilts just a touch from the heat. Squeeze 0.5 lemon over the top.

    5 min

    Tip: Finish with a squeeze of lemon if you want it extra sharp and bright.

Chef's Notes

This dish is basically my love letter to “winter, but make it lively.” Blood oranges show up for a hot minute, and I use them like a shortcut to instant restaurant energy—bright acidity, a little sweetness, and that gorgeous color. Substitutions I actually endorse: navel oranges instead of blood oranges; broth instead of wine. What I don’t love: skipping the sear—those browned bits are the whole sauce.
