Prep the fennelTrim the stalks, reserve some fronds for garnish, remove any tough outer layers, and cut each fennel bulb into wedges.
Cook the pancettaHeat a large skillet over medium heat. Add the diced pancetta and cook for 3–4 minutes, until it renders its fat and begins to crisp. Remove half the pancetta pieces with a spoon and set aside for garnishing later, leaving the rest and the fat in the pan.
Sear the fennelAdd the olive oil and butter to the pancetta fat. Once melted, add the fennel wedges in a single layer. Sear for 3–4 minutes per side until lightly golden. Season with salt and pepper.
Add garlic + deglazeStir in the sliced garlic and cook for 30 seconds. Pour in the white wine and let it reduce by half.
Braise the fennelAdd the broth, cover the skillet, reduce heat to medium-low, and simmer for 10–12 minutes, or until the fennel is tender.
Make the oreganata toppingIn a bowl, mix the breadcrumbs, Parmesan, oregano, parsley, lemon zest, olive oil, salt, and pepper. The mixture should be moistened but crumbly.
BroilPreheat the broiler. Transfer the fennel and its cooking juices to a baking dish (or leave in an oven-safe pan). Sprinkle the oreganata topping evenly over the fennel. Broil for 2–3 minutes, or until golden and crisp.
ServeTop with the reserved crispy pancetta, a squeeze of fresh lemon juice, and fennel fronds.
