Ingredients

2 lbs ground beef
1 lb ground pork
1 cup breadcrumbs
1 cup milk
1 medium egg
1 teaspoon salt
2 medium onions, finely chopped
½ cup butter

Onion Sauce:

3 cups onions, thinly sliced
1 cup butter
6 tablespoons flour
1 teaspoon salt
2 ½ cups beef broth
½ cup milk

Equipment Needed

Large bowl
Large skillet or frying pan
Saucepan
Spatula or wooden spoon

Instructions

Begin by preparing the breadcrumbs. In a large bowl, soak the breadcrumbs in the milk. This step is crucial for ensuring tender and moist meatballs. Let them sit for at least 5 minutes, allowing the breadcrumbs to fully absorb the milk.
In the same bowl, combine the soaked breadcrumbs with the ground beef, ground pork, egg, salt, and the finely chopped onions. Use your hands to gently mix all the ingredients together until just combined. Avoid overmixing, as this can result in tough meatballs.
Once the mixture is well combined, form the meat mixture into walnut-sized meatballs. Try to keep the meatballs uniform in size so that they cook evenly.
In a large skillet or frying pan, melt the ½ cup of butter over medium heat. Once the butter is melted and shimmering, carefully add the meatballs to the pan, ensuring not to overcrowd it. You may need to work in batches to properly brown the meatballs.
Brown the meatballs on all sides until they are nicely seared and golden brown. This step is essential for developing a rich flavor and creating a beautiful crust on the meatballs. Be patient and avoid moving the meatballs around too much while they are browning.
Once the meatballs are browned, cover the skillet and reduce the heat to low. Simmer the meatballs for 1 hour, allowing them to cook through and become incredibly tender. Be sure to check on them occasionally to ensure they are not sticking to the bottom of the pan. Add a splash of water or broth if needed to prevent sticking.
While the meatballs are simmering, prepare the onion sauce. In a separate saucepan, melt the 1 cup of butter over medium heat. Add the thinly sliced onions to the melted butter and sauté them until they are caramelized and deeply golden brown. This process will take time, so be patient and stir the onions frequently to prevent them from burning. The caramelized onions are the key to a flavorful and delicious sauce.
Once the onions are beautifully caramelized, blend in the flour and salt. Stir constantly for about 1-2 minutes to cook the flour and create a roux. This step will help thicken the sauce.
Slowly add the beef broth and milk to the onion mixture, whisking constantly to prevent lumps from forming. Continue to stir the sauce until it thickens to your desired consistency.
After the meatballs have simmered for an hour, pour the onion sauce over the meatballs in the skillet. Stir gently to coat the meatballs in the sauce.
Serve the meatballs in onion sauce immediately.

Expert Tips & Tricks

For an even richer flavor, use a combination of bone broth and regular beef broth in the sauce.
To add a touch of sweetness, stir in a teaspoon of brown sugar or a splash of balsamic vinegar to the onion sauce during the last few minutes of cooking.
If the sauce is too thick, add a little more beef broth or milk to thin it out. If the sauce is too thin, simmer it for a few more minutes to allow it to reduce and thicken.
For make-ahead prep, you can prepare the meatballs and onion sauce separately, then combine them and simmer just before serving. The flavors will meld together even more beautifully this way.
Use a meat thermometer to check the internal temperature of the meatballs; they should reach 160°F (71°C).

Serving & Storage Suggestions

Serve these delicious meatballs in onion sauce over egg noodles, mashed potatoes, or rice for a comforting and satisfying meal. Garnish with fresh parsley or chopped chives for a pop of color and freshness.

Leftover meatballs in onion sauce can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, simply warm them in a saucepan over medium heat, stirring occasionally, until heated through. You can also reheat them in the microwave, but be sure to cover them to prevent splattering. For longer storage, you can freeze the meatballs in onion sauce for up to 2-3 months. Thaw them in the refrigerator overnight before reheating.

Variations & Substitutions

For a spicier kick, add a pinch of red pepper flakes or a dash of hot sauce to the meatball mixture or onion sauce.
If you don’t have beef broth, you can use chicken broth or vegetable broth instead.
For a richer sauce, add a splash of heavy cream or sour cream to the onion sauce at the end of cooking.
Experiment with different types of ground meat, such as ground turkey or ground chicken, for a lighter version.
If you’re gluten-free, use gluten-free breadcrumbs in the meatball mixture and substitute cornstarch or tapioca starch for the flour in the onion sauce.

FAQs (Frequently Asked Questions)

Q: Can I use dried onions instead of fresh onions?
A: While fresh onions are highly recommended for their superior flavor and texture, you can substitute dried onions in a pinch. Use about 1/4 cup of dried minced onion for every medium fresh onion. Be sure to rehydrate the dried onions in warm water before adding them to the recipe.

Q: What if my meatballs fall apart during cooking?
A: This can happen if the meatball mixture is too wet or if you are not gentle enough when handling the meatballs. To prevent this, make sure the breadcrumbs are not overly soaked and avoid overmixing the meatball mixture. Also, be gentle when browning the meatballs and avoid moving them around too much.

Q: Can I bake the meatballs instead of frying them?
A: Yes, you can bake the meatballs if you prefer. Preheat your oven to 375°F (190°C) and place the meatballs on a baking sheet lined with parchment paper. Bake for 20-25 minutes, or until they are cooked through.

Q: How can I prevent the sauce from sticking to the pan?
A: To prevent the sauce from sticking to the pan, use a heavy-bottomed saucepan and stir the sauce frequently. You can also add a little bit of butter or oil to the pan before adding the sauce. If the sauce does start to stick, reduce the heat to low and continue stirring until it is thickened.

Q: Can I add other vegetables to the onion sauce?
A: Absolutely! Feel free to add other vegetables to the onion sauce, such as mushrooms, carrots, or celery. Sauté the vegetables along with the onions until they are tender before adding the flour and broth.
