Bison Meatballs Baked in Hoisin Sauce (Marvin)

Introduction

These bison meatballs are cooked in hoisin sauce and shaped into tapered cylinders—called Marvins—that stay moist because they’re baked in a covered dish rather than pan-fried. The spice blend of cumin, coriander, cloves, and peppercorns is ground fresh, which gives the meat deep, layered flavor without overwhelming it. Serve them as a main course with rice, or cut them smaller and use them as an 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: Substitute ground bison with the same weight of ground beef or lamb. The cook time remains the same; lamb will yield a slightly richer, more gamey result.

White rice or quinoa: Use white rice or cooked quinoa instead of the rice specified. Both will absorb the hoisin glaze equally well and keep the meatballs tender.

Fresh cilantro or mint: Replace basil with cilantro or mint for a different herbal note. Cilantro brightens the hoisin sauce; mint adds cooling contrast.

Soy glaze variation: Mix equal parts hoisin sauce and low-sodium soy sauce, then brush over the meatballs before baking. This adds saltiness and umami depth while cutting the sweetness of hoisin alone.

Scaled batch cooking: Double the recipe and freeze half the shaped, uncooked meatballs on a tray, then transfer to a freezer bag. Bake directly from frozen, adding 5–7 minutes to the cook time.

Tips for Success

Microwave the onion and garlic first: This softens them so they distribute evenly through the meat without requiring extra chopping. Skip this step and the raw onion texture will be too pronounced.

Don’t overwork the mixture: Stir just until combined. Overworking compacts the meat and makes the meatballs dense rather than tender.

Shape with slightly damp hands: Wet your hands lightly before shaping each cylinder so the mixture doesn’t stick and tear. The tapered shape matters because the thinner ends cook through without the thicker middle drying out.

Check doneness by internal temperature: A meat thermometer inserted into the center of the largest meatball should read 160°F (71°C). If it’s below 155°F at the 20-minute mark, add 3–5 minutes and check again.

Use the hoisin sauce as your glue: Brush it on generously so it coats the meatballs and pools slightly in the baking dish. This creates a light glaze that keeps them moist during baking.

Storage and Reheating

Store cooked meatballs in an airtight container in the refrigerator for up to 3 days. They keep their shape and flavor well. Freeze in a single layer on a tray for 2 hours, then transfer to a freezer bag for up to 2 months.

FAQ

Can I prepare the meat mixture ahead and refrigerate it?

Yes. Mix everything except the hoisin sauce, cover, and refrigerate for up to 8 hours. Shape and coat with hoisin just before baking—don’t let shaped meatballs sit in the sauce uncooked for more than 30 minutes or they’ll absorb too much liquid.

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

Use a spice grinder, coffee grinder, or even a zip-top bag and rolling pin to crush the seeds and peppercorns coarsely. You need texture, not powder, so don’t overprocess.

Can I use store-bought ground spice blends instead of grinding whole spices?

You can, but the flavor will be noticeably flatter. Whole spices are fresher and more aromatic. If you must use ground spices, reduce each to ⅛ teaspoon and mix them with the salt first to distribute evenly.

Will these work as a freezer meal?

Partly. You can freeze the shaped, uncooked meatballs, then bake them straight from frozen (adding 5–7 minutes to the time). However, don’t coat them with hoisin sauce before freezing; do that right before baking so the sauce doesn’t separate or become watery.
