A thick bone-in pork chop becomes a complete French bistro dinner with crisp Lyonnaise potatoes, colourful vegetables, and a mushroom cognac cream sauce. The key is to brown the meat well without overcooking it, then let it rest while the sauce comes together in the same pan.

This recipe is based on my original YouTube video, with a few adjustments to make the quantities and cooking temperatures easier to reproduce at home. It is an abundant plate, but preparing the vegetables separately gives every part its own texture instead of turning the meal into one heavy mixture.

What Makes This Pork Chop Different

In French cooking, a côte de porc garnie is a substantial bone-in pork chop served with several carefully prepared garnishes. Here, those garnishes include thinly sliced Lyonnaise potatoes, carrots, cauliflower, endives, and mushrooms finished with cognac and cream.

I make the components separately because they do not cook at the same speed. The potatoes need a dry, hot surface to become crisp, while the carrots and cauliflower need only enough time in the pan to pick up some colour. The pork deserves the closest attention. A fixed cooking time is unreliable because a one-inch chop and a two-inch chop behave very differently.

This is more elaborate than my quicker air fryer pork chops and less sauce-forward than pork chops with garlic and mushrooms. It is the kind of plate I make for a relaxed weekend dinner or when I want a traditional bistro presentation.

Ingredients You Need

Choose a thick bone-in pork chop with some visible fat around the edge. The bone slows heat transfer slightly and helps protect the meat, but thickness matters more than weight when estimating the cooking time.

Duck fat gives the potatoes and vegetables their characteristic savoury flavour. You do not need a deep layer in every pan. A thin coating is enough to promote browning without making the finished plate greasy.

For the sauce, use heavy cream rather than milk or low-fat cooking cream. The cognac and tomato introduce acidity, and a higher-fat cream remains smooth as the sauce reduces.

1 thick bone-in pork chop, about 1 pound

1 pound Yukon Gold or yellow potatoes

1 medium onion

2 small carrots

¼ medium cauliflower

2 small Belgian endives

5 ounces cremini or white mushrooms

1 small Roma tomato

3 tablespoons duck fat, divided

2 tablespoons cognac

½ cup heavy cream

Kosher salt

Freshly ground black pepper

Chopped parsley, optional

Before You Start

Preheat the oven to 350°F. Pat the pork chop dry and leave it at room temperature for about 15 minutes while preparing the vegetables. Dry meat colours more readily, while surface moisture causes it to steam.

Slice the potatoes evenly, about one-eighth inch thick. A mandoline is useful, but a sharp knife works as long as the slices are consistent. Remove the small hard cone from the base of each endive so it cooks evenly and tastes less bitter.

The vegetables are briefly boiled before they are browned. Do not cook them until completely soft in the water. They still need enough structure to survive draining, handling, and a final turn in the hot pan.

Step-by-Step Instructions

1. Blanch the potatoes

Bring a large pot of salted water to a boil. Add the sliced potatoes and wait for the water to return to a simmer. Cook for 2 minutes, then drain thoroughly.

Spread the slices on a clean kitchen towel or tray for a few minutes. What I look for here is a potato slice that bends slightly but does not break apart. The surface should look dry before it goes into the hot fat.

2. Precook the vegetables

Return the water to a boil and add the carrots. Cook for about 8 to 10 minutes, depending on their thickness, until a knife enters with slight resistance.

Remove the carrots, then cook the endives for 12 to 13 minutes. Drain them well and press gently to remove trapped water. Finally, boil the cauliflower florets for approximately 4 to 5 minutes. They should be tender at the edges but firm in the centre.

3. Cook the Lyonnaise potatoes

Heat 1½ tablespoons of duck fat in a large oven-safe skillet over medium-high heat. Add the potatoes and half the sliced onion, season lightly, and arrange them in as even a layer as possible.

Let the underside begin to colour before moving anything. Place the skillet in the oven for 15 to 20 minutes, turning the potatoes after about 10 minutes. They are ready when the edges are deep golden and crisp while the centres remain creamy. For a quicker alternative, try my air fryer roasted potatoes.

4. Sear and finish the pork chop

Season the pork with salt and pepper. Heat 1 tablespoon of duck fat in a heavy oven-safe skillet over medium-high heat. When the fat shimmers, add the chop and leave it undisturbed for 2 to 3 minutes.

Turn the chop when the first side has formed a dark golden crust and releases without tearing. Brown the second side for another 2 to 3 minutes, then briefly hold the fatty edge against the pan to colour it.

Transfer the skillet to the oven. Cook until the centre approaches 142 to 145°F, checking early with an instant-read thermometer inserted away from the bone. Remove the chop and let it rest for 5 minutes, verifying that it reaches 145°F during the rest.

The mistake to avoid is relying on colour alone. Properly cooked pork can remain faintly pink, while an overcooked chop can still look pink close to the bone. Temperature is the dependable measure.

5. Brown the vegetables

Heat the remaining duck fat in a wide skillet. Add the drained carrots and cook until their surfaces develop small caramelized patches. Add the cauliflower and endives, working in batches if the pan becomes crowded.

Turn the vegetables carefully so they colour without falling apart. Taste before adding more salt because they were cooked in salted water. Keep them warm while making the sauce.

6. Prepare the cognac mushroom sauce

Slice the mushrooms and finely chop the remaining onion. Seed and dice the tomato.

Use the pork skillet with its browned cooking residue. Pour off excess fat, leaving approximately one teaspoon behind. Add the onion and mushrooms and cook over medium-high heat until the mushrooms release their liquid and the pan becomes nearly dry again.

Add the tomato and cook for 1 to 2 minutes. Remove the skillet from the burner before pouring in the cognac. Return it to medium heat and let the alcohol reduce until only a thin glaze remains. Flambéing is optional and should only be attempted away from an exhaust fan, curtains, and other flammable materials.

Pour in the cream and simmer gently for 2 to 4 minutes. Scrape the browned residue from the bottom of the skillet as the sauce reduces. It is ready when it coats the back of a spoon but still flows easily. If it becomes too thick, loosen it with a tablespoon of water.

The same attention to reduction is useful when making a creamy mushroom pan sauce or a smooth Dijon cream sauce.

Assemble the Plate

Arrange the crisp potatoes, carrots, cauliflower, and endives around the pork chop. Spoon the mushroom cognac sauce beside or partially over the meat so the crust remains visible. Finish with chopped parsley if desired.

When sliced, the centre should be moist and lightly pink, not grey and fibrous. The potatoes should have browned edges, and the sauce should be glossy rather than thick like gravy.

Substitutions

Butter or neutral oil can replace the duck fat. Butter gives good flavour but browns quickly, so combine it with a little oil when working over medium-high heat.

Brandy can replace cognac in the same quantity. For an alcohol-free sauce, use unsalted chicken stock and allow it to reduce before adding the cream. Broccolini or green beans can replace the cauliflower. Boneless pork chops also work, but they cook faster and should be checked several minutes earlier.

For a sharper sauce, stir in a teaspoon of Dijon mustard after adding the cream. A full pork tenderloin with Dijon sauce is a better choice when mustard is meant to be the main flavour.

FAQ

Can I prepare the vegetables in advance?

Yes. Blanch the carrots, cauliflower, and endives several hours ahead, drain them thoroughly, and refrigerate them separately. The potatoes are best blanched shortly before cooking because their surfaces can darken and become sticky during storage.

How do I keep a thick pork chop juicy?

Use a thermometer and stop cooking according to internal temperature rather than time. Let the chop rest before slicing, and do not cover it tightly with foil because trapped steam can soften the crust.

Why are my potatoes not becoming crisp?

They may be too wet, crowded, or moved too soon. Dry the blanched slices, use a large skillet, and allow the first side to develop colour before turning.

Do I have to flambé the cognac?

No. Letting the cognac simmer and reduce accomplishes the important part by concentrating its flavour and removing much of the harsh alcohol aroma.

Can I make this with several pork chops?

Yes, but do not crowd the skillet. Brown the chops in batches, then finish them together on a sheet pan in the oven. Check each chop individually because thickness and bone placement affect cooking time.
