1-Step 1: Prepare the Meatball Mixture Start by combining all meatball ingredients in a large mixing bowl. Add the panko breadcrumbs, grated onion, milk, ground beef, egg, nutmeg, allspice, salt, and pepper. Using your hands or a wooden spoon, gently mix everything together until just combined. Be careful not to overwork the mixture, as this can make the meatballs tough and dense. Once mixed, form the mixture into small meatballs using about 2 tablespoons of mixture per ball. Aim for uniform size, approximately 1 inch in diameter, so they cook evenly. You should get around 24-28 meatballs from one pound of beef.

2-Step 2: Brown the Meatballs Heat the olive oil in a large skillet or Dutch oven over medium-high heat. When the oil shimmers and is hot but not smoking, carefully add the meatballs in batches. Don’t overcrowd the pan, as this causes steaming rather than browning. Work in 2-3 batches depending on your pan size. Brown the meatballs on all sides, turning them every 1-2 minutes. You’re looking for a golden-brown crust, not fully cooked through at this stage. The meatballs will finish cooking in the sauce. Once browned, transfer them to a paper towel-lined plate to drain excess oil.

3-Step 3: Build the Creamy Sauce Base In the same skillet (don’t clean it those browned bits add flavor), pour in the chicken broth, heavy cream, Worcestershire sauce, Dijon mustard, salt, and pepper. Use a wooden spoon or whisk to combine everything, scraping up any browned bits from the bottom of the pan. These fond bits add tremendous depth to your sauce. Bring the mixture to a gentle boil over medium-high heat. You’ll see small bubbles forming around the edges. Reduce the heat immediately to maintain a simmer rather than a rolling boil, which could cause the cream to separate.

4-Step 4: Cook the Pasta in the Sauce Add the dry pasta directly to the simmering sauce. This one-pot method allows the pasta to absorb flavor from the sauce while releasing starch that helps thicken everything naturally. Stir frequently to prevent sticking, especially during the first few minutes. Cook the pasta for 10-12 minutes, stirring often, until the noodles are tender and the sauce has thickened to coat the back of a spoon. The sauce will continue thickening as it cools, so don’t worry if it seems slightly thin. Taste-test a noodle around the 10-minute mark to check for doneness.

5-Step 5: Finish and Serve Once the pasta is tender, stir in the freshly grated Parmesan cheese until melted and smooth. Gently fold in the browned meatballs, being careful not to break them apart. Simmer everything together for 2-3 minutes to heat the meatballs through completely. Taste the sauce and adjust the seasoning with additional salt and pepper if needed. The flavors should be well-balanced creamy, savory, with a hint of warmth from the spices. Remove from heat and sprinkle with fresh chopped parsley for a pop of color and freshness. Serve immediately in shallow bowls, making sure each portion gets plenty of meatballs and sauce. A side of crusty bread or a simple green salad completes the meal perfectly.
