Mushroom Glazed Bison Meatloaf That Stays Juicy

Bison is leaner than beef by a wide margin. Ground bison usually runs around 90/10 and sometimes leaner, where a good beef meatloaf mix is 80/20. That gap is the entire problem with bison meatloaf, and it is why most of them come out of the oven dense and dry. The answer is not to cook it less, since ground meat still needs to reach a safe temperature. The answer is to put moisture and fat back in before it ever goes in the oven.

We do that three ways: a panade of fresh breadcrumbs soaked in milk, finely chopped bacon worked through the mix, and half a pound of mushrooms cooked down until their water is gone and their flavor is concentrated. The mushrooms do double duty, adding savory depth and holding moisture in the crumb.

The glaze is where the mushrooms show up again, this time as dried porcini ground to a powder and stirred into a sweet and sour tomato base. It bakes onto the loaf in two coats and goes dark and glossy.

Why this bison meatloaf works

• A real panade. Bread soaked in milk traps moisture in a gel that survives the oven. Dry breadcrumbs stirred in do the opposite and pull water out.
• Added fat, on purpose. Four ounces of chopped bacon brings a lean mix up to roughly where beef starts, without making it taste like bacon.
• Mushrooms cooked dry first. Raw mushrooms release water into the loaf and it steams. Cooked down first, they add flavor and structure instead.
• Free form on a sheet pan. A loaf pan steams the sides. Shaped by hand on a tray, the whole outside browns and the glaze sets on five faces rather than one.
• Porcini powder in the glaze. It gives the sweet tomato glaze a savory backbone so it reads as a sauce rather than as ketchup.

Ingredients

For the meatloaf

• 2 lb ground bison (900 g)
• 4 oz bacon (115 g), chopped very fine, or 4 oz ground pork fat
• 1 cup fresh breadcrumbs (50 g), torn from day old bread
• 1/2 cup whole milk (120 ml)
• 8 oz cremini mushrooms (225 g), chopped fine
• 1 onion, diced fine
• 3 garlic cloves, minced
• 1 tbsp butter
• 2 eggs, beaten
• 2 tbsp Worcestershire sauce
• 1 tbsp Dijon mustard
• 2 tsp fresh thyme leaves
• 2 tsp kosher salt, 1 tsp black pepper

For the mushroom glaze

• 1/2 oz dried porcini (14 g), ground to a powder in a spice grinder
• 1/2 cup ketchup (120 g)
• 2 tbsp tomato paste
• 2 tbsp dark brown sugar
• 1 tbsp cider vinegar
• 1 tbsp soy sauce

Substitutions: ground beef at 85/15 works with the bacon left out. Store bought mushroom powder replaces the ground porcini. For a dairy free panade, soak the bread in unsweetened oat milk or stock instead.

Method

1. Make the panade. Tear the bread into a bowl, pour the milk over, and leave it 10 minutes. Mash it to a rough paste with a fork. It should look like wet dough, not like soup.
2. Cook the mushrooms dry. Heat a dry skillet over medium high, add the chopped mushrooms, and cook 8 minutes, stirring, until they release their water and the pan goes dry again. Add the butter, onion and garlic and cook 6 minutes more until soft. Spread this on a plate to cool.
3. Mix the glaze. Stir the porcini powder, ketchup, tomato paste, brown sugar, vinegar and soy sauce together. Set it aside.
4. Combine. In a wide bowl put the bison, chopped bacon, cooled mushroom mixture, panade, eggs, Worcestershire, Dijon, thyme, salt and pepper.
5. Mix gently and briefly. Work it with your hands just until everything is evenly distributed, about 45 seconds. Meatloaf is the opposite of kofta. Overworking it makes the texture springy and tight.
6. Shape it. Turn the mixture onto a parchment lined sheet pan and shape a loaf about 9 inches long and 4 inches wide, with the top gently rounded. Smooth the surface with wet hands.
7. First bake. Bake at 350F (175C) for 40 minutes.
8. Glaze twice. Brush half the glaze over the loaf and bake 15 minutes. Brush the rest on and bake a final 10 to 15 minutes, until the glaze is dark and tacky.
9. Check the temperature. Ground meat wants 160F (71C) at the center. Between the panade, the bacon and the mushrooms, this loaf stays moist at that temperature, which a plain lean mix will not.
10. Rest. Fifteen minutes before slicing. Cut it hot and the slices fall apart and the juices run onto the board.

Pro tips and common mistakes

• Never skip the panade. With a lean grind it is the single thing standing between you and a dry loaf.
• Cool the mushrooms before mixing. Warm vegetables start cooking the egg and the fat before the loaf is even shaped.
• Do not use a loaf pan. The sides steam in their own juices and you lose most of the surface area the glaze wants.
• Mix with your hands, not a machine. A stand mixer overworks it in seconds. We use hands and a wooden spoon, and no plastic near the hot pan.
• Grind the porcini finely. Coarse pieces in the glaze will not soften during baking and read as grit.

Storage and leftovers

Refrigerated it keeps 4 days and slices far more cleanly cold than warm. Reheat slices in a covered pan with a splash of water over low heat, or eat them cold, which is the traditional and better answer.

It freezes 3 months, sliced and separated so you can take out what you need. A cold slice on buttered bread with mustard and a pickled onion is the reason to make a loaf this size in the first place. Leftovers also crumble well into a quick pasta sauce.

What to serve with it

• Mashed potatoes, the obvious and correct pairing.
• Roasted carrots with thyme, cooked on a second tray at the same temperature.
• Buttered green beans with lemon.
• A sharp slaw if you want something cold against the glaze.

Frequently asked questions

Why is bison meatloaf drier than beef?

Because ground bison is usually around 90/10 where beef meatloaf mix is 80/20. That missing fat is what normally keeps the crumb soft, so it has to be replaced with a panade and some added fat.

Do I have to add bacon?

Not if you can get ground pork fat or fatback from a butcher, which is the cleaner option since it adds fat without smoke. Some ground bison is sold blended with pork fat already, and that works straight from the package.

Can I make it ahead?

Yes. Shape the loaf up to a day ahead and keep it covered in the fridge on its tray. Add about 10 minutes to the first bake since it starts cold. The glaze should be brushed on during baking, not before.

Why did my meatloaf crack on top?

Usually the oven was too hot or the mix was too dry. Cracking is cosmetic and the glaze fills it, but if it bothers you, smooth the surface with wet hands and check your oven with a separate thermometer.

Can I use dried mushrooms in the loaf as well?

You can, and it deepens the flavor. Soak 1/2 oz of dried porcini, chop them, and add them with the cooked fresh mushrooms. Use the soaking liquid in place of some of the milk in the panade.

Where to buy the bison

Most ground bison comes from the chuck, which is why it is flavorful even at a low fat percentage. Ranch raised bison is almost always grass fed and finished, and the taste difference between producers is noticeable. Find one near you through our Find a Farmer directory, and ask whether they can grind you a batch with some fat left in.
