Bison Meatballs Baked in Hoisin Sauce (Marvin)

Introduction

These bison meatballs, called Marvins, are shaped into tapered cylinders and baked in hoisin sauce for a savory, slightly sweet dish that comes together in under an hour. The ground bison is bound with cooked rice and seasoned with a spice blend you toast and grind yourself, giving it depth that store-bought seasoning mixes can’t match. This works as a main dish over rice or noodles, or as a substantial appetizer.

Recipe Details

• Prep Time: 25 minutes
• Cook Time: 25 minutes
• Total Time: 50 minutes
• Servings: 4

Ingredients

• 1 large red onion
• 2 garlic cloves, minced
• ¼ teaspoon cumin seeds
• ¼ teaspoon coriander seeds
• 3 peppercorns
• 2 whole cloves
• ¼ teaspoon sea salt
• 1 lb (450 g) ground bison meat
• ½ cup cooked rice
• 10 large basil leaves, julienned
• 1 teaspoon canola oil
• ½ teaspoon fish sauce
• Hoisin sauce

Instructions

1. Preheat oven to 425°F (220°C).
2. Oil the bottom of a 9×12-inch Pyrex baking dish.
3. Thinly slice the onion to create long thin slices.
4. Microwave the onion slices and garlic on high for 5 minutes.
5. Grind the cumin, coriander, peppercorns, cloves, and salt together using a mortar and pestle.
6. Roughly mix the softened onions and garlic, bison, rice, spice grind, fish sauce, and basil.
7. Shape the meat mixture into tapered cylinders (similar to small sweet potatoes) and place into the baking dish. The Marvins should be about 1¼ inch diameter in the middle and 5 inches long.
8. Coat the Marvins with hoisin sauce.
9. Bake for 20-25 minutes in the preheated oven.

Variations

Beef or lamb base: Swap the ground bison for ground beef or lamb. The cooking time and hoisin coating remain the same; lamb will deliver a deeper, more aromatic result.

Fresh ginger addition: Add ½ teaspoon minced fresh ginger to the meat mixture for warmth and a sharper edge against the hoisin sweetness.

Cilantro instead of basil: Replace the basil with fresh cilantro for a brighter, more herbaceous finish that pairs well with hoisin.

Serve with a sauce dip: Whisk 2 tablespoons of hoisin sauce with 1 tablespoon of rice vinegar and a pinch of chili flakes to create a tangy dipping sauce alongside the baked Marvins.

Double the spice blend: If you prefer a more pronounced spiced flavor, increase each seed and spice quantity by 50% and grind together as directed.

Tips for Success

Toast your spices before grinding: If you have time, dry-toast the cumin, coriander, peppercorns, and cloves in a small pan over medium heat for 1–2 minutes before grinding. This deepens their flavor considerably.

Don’t overmix the meat: Combine the meat, rice, and seasonings with a light hand. Overworking the mixture compacts it and makes the Marvins dense; a rough mix yields a more tender result.

Shape while the onion and garlic are still warm: Work quickly after microwaving so the softened onions bind more easily into the meat mixture and help hold the cylinders together.

Check doneness by internal temperature: Bison is very lean and can dry out if overcooked. Use an instant-read thermometer to confirm the center of the thickest Marvin reaches 160°F; don’t rely on visual cues alone.

Hoisin coating thickness matters: Don’t oversaturate the Marvins. A single even coat is enough; excess sauce will pool and create a soggy bottom crust.

Storage and Reheating

FAQ

Can I use uncooked rice instead of cooked rice?

No. Uncooked rice won’t bind the meat mixture and will absorb too much moisture during baking, creating a dry, crumbly texture. Always use cooked rice that has cooled.

How do I know if the cylinders are shaped correctly?

They should be tapered (slightly thinner at the ends) and approximately 5 inches long with a 1¼-inch diameter at the center. Think of a small potato shape. If they’re too thick or stumpy, they won’t cook evenly.

Can I prepare the Marvins the night before and bake them the next day?

Yes. Shape them, arrange them in the oiled baking dish, cover tightly with plastic wrap, and refrigerate. Coat with hoisin sauce and bake directly from the cold state, adding 5–7 minutes to the bake time to ensure the centers reach 160°F.

What if I don’t have a mortar and pestle?

A spice grinder or a small food processor works well. Pulse the whole spices and salt until finely broken down. A pinch mill or even a rolling pin and a small bowl will work in a pinch, though the texture will be coarser.
