Trim and wash broccoli, cut into florets. Cook in salted water (enough to cover) for 5 minutes over medium heat. Peel and chop shallots.
Wash pork fillet and pat dry. Cut into 8-10 medallions. Wrap each medallion with 1 slice of bacon. Heat oil in a large pan over medium-high heat. Fry medallions 2-3 minutes per side until the internal temperature reaches 63°C / 145°F. Season with salt and pepper. Remove from pan and set aside.
In the same pan with the frying fat, cook shallots over medium heat until translucent, about 3 minutes. Stir in honey and cook for 1 minute to caramelize. Pour in white wine or broth and bring to a boil. Remove from heat. Stir in crème fraîche and both mustards. Season to taste with salt and pepper.
Drain broccoli thoroughly. Transfer to a greased baking dish. Layer cooked medallions on top. Pour sauce over everything. Toast bread slices until crispy, then roughly crumble. Mix breadcrumbs with Provence herbs. Sprinkle over medallions.
Spread 2 tablespoons butter in flakes over the top. Bake in a preheated oven at 228°C / 442°F (conventional heat), 200°C / 392°F (convection), or gas mark 4 for about 10 minutes until golden brown. Serve with boiled potatoes.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
