What You’ll Need to Make the Meatballs

Ground Beef and Ground Pork: A blend for tender, juicy meatballs.
Yellow Onion: Finely chopped for that savory bite.
Garlic Cloves: Minced, because garlic makes everything better. You can adjust the measurements according to your love for garlic. I obviously love garlic! The more, the better.
Eggs: To bind everything together.
Breadcrumbs: For structure and texture.
Worcestershire Sauce: A splash for depth of flavor.
Salt and Cayenne Pepper: Just enough to season and bring a little heat.

For frying:

Flour: For dredging.
Cajun Seasoning: Mixed in the flour to add a bit of spice to amp up the flavor. You can get it on Amazon if you can’t find it in your local food store. Or feeling adventurous? You can make your own.
Vegetable Oil: For frying those meatballs to perfection.

Building the Sauce

Yellow Onions: Two cups, thinly sliced. I suggest using a mandoline slicer. My boys just gifted me this one from Amazon, and it works great.
Beer: I suggest using amber beer because it adds depth and adds to that rich color to the gravy. Avoid light beer, which won’t provide the same robust flavor profile.
Beef Broth: For richness and flavor. I like to use low-sodium beef broth to control the salt.
Parsley: Chopped for a fresh finish.

Assembling the Meatball Hero

French Loaf: I love a French loaf because it perfectly balances texture and strength to handle the hearty filling and saucy goodness. Other great options include ciabatta or a sturdy baguette.
Whole Grain Mustard: For tangy zip.
Mayonnaise: It adds a rich, velvety layer that ties everything together.
Provolone Cheese: Melted over the meatballs for that gooey, cheesy goodness.

How to Make This Meatball Hero

Step 1: Prepare the Meatballs

In a large mixing bowl, combine ground beef, ground pork, finely chopped yellow onion, minced garlic, eggs, breadcrumbs, Worcestershire sauce, cayenne pepper, and a pinch of salt. Mix gently with your hands until all the mixture is combined.
Roll the mixture into evenly sized-meatballs (about 1.5 inches in diameter). Makes about 20 meatballs.
Mix Cajun seasoning into the flour and season with salt. Dredge the meatballs lightly in flour, shaking off any excess flour. Reserve the leftover flour.
Heat vegetable oil in a large skillet over medium heat. Once the oil is hot, fry the meatballs in batches, ensuring they aren’t touching. Roll gently with a fork until browned on all sides, about 8-10 minutes per batch. Remove and set aside on a plate lined with a paper towel.

Step 2: Make the Gravy

In the same skillet, add the thinly sliced yellow onions, season with salt, and sauté until slightly caramelized, scraping up any browned bits at the bottom with a wooden spoon, about 5 minutes. Add the reserved flour and stir with the onions until the mixture thickens.
Slowly pour beer and beef broth into the pan and whisk to combine all the ingredients, allowing the sauce to thicken.
Add parsley for a fresh finish, then return the meatballs to the skillet. Simmer on medium-low heat for about an hour, stirring every 15 minutes. If the sauce thickens too much, add 1/2 cup of water or more to achieve the desired consistency.

Step 3: Assemble the Meatball Hero

Cut the loaf in half and spread a layer of whole-grain mustard on one side and a layer of mayonnaise on the other.
Next, layer provolone slices on each side of the loaf.
Spoon meatballs on one side of the loaf and top with a generous amount of sauce.
Garnish with some chopped fresh parsley and fold that baby up. Slice and serve immediately. Oh, and pour yourself a nice cold beer.

Make Ahead and Storage Tips

The beauty of this Meatball Hero is how well it works as a make-ahead recipe. Here’s how to prepare and store it:

Prepare in advance: Make the meatballs and sauce a day ahead. Let both cool completely before storing. Just don’t arrange the meatballs on the loaf until ready to serve.
Refrigeration: Meatballs can be stored in the sauce in an airtight container in the refrigerator for up to 2 days.
Reheating: When ready to serve, reheat the meatballs in the sauce in a saucepan over low heat until warmed through, about 20 minutes, stirring throughout.
Freezing: For longer storage, freeze the cooked meatballs and sauce in separate freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.

Potluck Fun

If you’re bringing to a potluck (love me a potluck), arrange the whole meatball hero and wrap it in tinfoil. Heat in the oven before serving for about 15-20 minutes at 325. Ensures the bread gets crunchy and the cheese extra melty.

Variations

Extra Toasty and Melty: Wrap the assembled sandwiches in tinfoil and heat them in the oven for a toasty, melty finish.
Over Rice: Skip the bread and serve the meatballs and sauce over rice for a comforting option perfect for your peeps who want something other than bread.
Make it as Sliders: Use smaller rolls to create bite-sized sliders, ideal for parties or game day gatherings.
