Ingredients
Main Ingredients
– 1 lb ground beef
– 1/2 lb ground pork (optional)
– 1 large onion, finely chopped
– 3 cloves garlic, minced
– 1/2 cup breadcrumbs
– 1/4 cup grated Parmesan cheese
– 1 large egg
– 1/2 cup shredded Gruyère cheese (for topping)
Ground beef is the main star here. The pork adds a nice touch but is not required. Onions and garlic bring rich flavor. You will need breadcrumbs and Parmesan cheese to bind the meatballs and add taste. An egg helps hold everything together. Gruyère cheese makes a creamy topping that melts perfectly over the meatballs.
Seasonings and Broth
– 1 tablespoon Worcestershire sauce
– 1 teaspoon dried thyme
– 1/2 teaspoon salt
– 1/4 teaspoon black pepper
– 1 cup beef broth
Worcestershire sauce gives depth to the flavor. Thyme adds a hint of earthiness. Salt and pepper enhance all the tastes. The beef broth serves as a warm base, making the dish comforting.
Optional Add-ons
– Fresh herbs for garnish
– Extra cheese for topping
– Spices like paprika or red pepper flakes
You can sprinkle fresh herbs for bright color and taste. Adding more cheese can make it extra special. If you like a kick, try spices like paprika or red pepper flakes for added heat.

Step-by-Step Instructions
Preparing the Caramelized Onions
To start, heat 1 tablespoon of olive oil in a skillet over medium heat. Add 1 large finely chopped onion. Sauté the onion until it turns golden brown. This takes about 15 to 20 minutes. Stir the onion often to prevent it from burning. After 15 minutes, add 3 cloves of minced garlic. Cook for another 5 minutes. The garlic will add flavor and aroma to your dish. Once done, set the onions aside to cool slightly.
Mixing the Meatball Ingredients
In a large bowl, combine the meat. Use 1 pound of ground beef and 1/2 pound of ground pork if you like. Next, add the cooled caramelized onions and garlic. Then, mix in 1/2 cup of breadcrumbs and 1/4 cup of grated Parmesan cheese. Crack 1 large egg into the bowl. Add 1 tablespoon of Worcestershire sauce, 1 teaspoon of dried thyme, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. Mix everything until well combined. This forms the base for your meatballs.
Baking and Simmering the Meatballs
Now, preheat your oven to 400°F (200°C). While it heats, shape the meat mixture into small meatballs. Aim for about 1 inch in diameter. Place them on a baking sheet lined with parchment paper. Bake the meatballs for 20 to 25 minutes. They should be cooked through and browned.
While the meatballs bake, pour 1 cup of beef broth into a saucepan. Heat it until it simmers. Once the meatballs are done, transfer them into the broth. Allow them to sit for 5 minutes. This helps them absorb the rich flavors. Serve the meatballs topped with 1/2 cup of shredded Gruyère cheese. Let the cheese melt before you dig in!
Tips & Tricks
Ensuring the Perfect Meatball Texture
To make great meatballs, you need the right texture. Use binding agents like breadcrumbs and eggs. They help hold the meatball together. The moisture from the meat and onions also adds to the softness. If your mix feels too dry, add a splash of beef broth. For richer flavor, consider adding a bit of grated cheese.
Flavor Enhancements
Adding spices can take your meatballs to the next level. Try different herbs like oregano or basil. A bit of hot sauce can add a nice kick. If you want a sweeter touch, mix in some minced bell peppers. You can also adjust the salt and pepper to fit your taste. Always taste your mix before cooking.
Cooking Techniques
You can cook your meatballs in many ways. Baking is easy and keeps them moist. However, you can also pan-fry them for a crispy outside. To pan-fry, heat some oil in a skillet. Cook the meatballs until they are brown on all sides. After that, simmer them in broth for extra flavor. This method gives you a nice crust and keeps them juicy.
Pro Tips
- Use Fresh Herbs: Fresh thyme can elevate the flavor of your meatballs significantly. If you have it on hand, consider substituting dried thyme with fresh for a more aromatic taste.
- Mix Meat Types: Combining ground beef with ground pork adds a nice flavor and moisture to your meatballs. If you’re open to it, try this combination for a richer taste.
- Don’t Overmix: When combining your ingredients, mix just until everything is incorporated. Overmixing can lead to tough meatballs, so be gentle!
- Cheese Melting Tip: For perfectly melted Gruyère cheese, place the meatballs back in the oven for a few minutes after adding the cheese. This will ensure a beautifully melted topping.

Variations
Different Meat Combinations
You can mix it up with different meats. Try turkey or chicken instead of beef. These options can make the dish lighter but still tasty. Ground turkey has a milder flavor. You can spice it up with extra seasonings. Ground chicken is also a great choice. It holds flavors well and stays juicy.
Vegetarian Adaptations
For a plant-based option, use lentils or mushrooms. Lentils give a nice texture and protein. Mushrooms add a deep, rich flavor. You can also use a meat substitute like tempeh or tofu. Just make sure to add enough spices to keep it flavorful. Use breadcrumbs made from whole grains for added nutrition.
Serving Styles
How you serve these meatballs can change the dish. Serve them in a shallow bowl with warm beef broth. Top with melted Gruyère cheese for a rich touch. You can also add fresh thyme for color and flavor. For a playful twist, serve them on skewers with a side of crusty bread. This makes them fun for gatherings. Another idea is to use a bed of mashed potatoes or polenta. This adds a creamy base that pairs well with the meatballs.
Storage Info
Storing Leftovers
To keep your meatballs fresh, store them in an airtight container. Place a layer of parchment paper between layers to avoid sticking. Make sure they cool down first. This keeps the flavors intact. You can store them in the fridge for up to three days. Just reheat them gently when you’re ready to enjoy again.
Freezing Instructions
Freezing is a great option if you want to save some meatballs for later. First, let them cool completely. Then, arrange the meatballs on a baking sheet in a single layer. Freeze them for about an hour. After that, transfer them to a freezer-safe bag or container. This method helps them keep their shape. They can last in the freezer for up to three months. When you’re ready to eat, thaw in the fridge overnight. Reheat them in a saucepan with beef broth for the best taste.
Shelf Life
In the fridge, meatballs can last for three days. If you freeze them, they stay good for about three months. However, for the best flavor, I recommend eating them sooner. Always check for signs of spoilage, like off smells or changes in texture. Enjoy your delicious meatballs while they’re fresh!
