A rich, hearty bolognese sauce made with lean ground beef, white wine, and whole milk, simmered low and slow until thick and deeply flavored. Worth every minute of the cook time.
Heat olive oil in a large stock pot over medium-high heat.
Add the diced onion, carrots, celery, and garlic and cook until the vegetables are tender and the onion is translucent, about 3 to 4 minutes.
Add the ground beef, salt, and pepper to the pot. Break the meat apart as it cooks until no pink remains, about 5 to 6 minutes.
Stir in the tomato paste and white wine.
Let it cook for 1 to 2 minutes until the alcohol cooks off and the tomato paste is fully worked into the meat mixture.
Pour in the crushed tomatoes and whole milk and add the bay leaf. Stir to combine.
Bring the sauce to a boil, then reduce the heat to low.
Simmer uncovered for 2 to 3 hours, stirring regularly, until the sauce has reduced by about half and thickened into a rich, hearty gravy.
Remove and discard the bay leaf before serving. Garnish with grated parmesan and fresh parsley.
Notes
Dice the onion, carrots, and celery small and as uniformly as possible - about ¼ inch. You don't want visible chunks of vegetable in the finished sauce.
Lean ground beef (93/7 or 96/4) works best. If you're using a higher fat ratio like 80/20, drain the excess fat from the pot before adding the tomato paste and wine.
Use a good quality dry white wine. The flavor concentrates as the sauce cooks. Pinot Grigio, Sauvignon Blanc, and Pinot Gris are all solid choices. To skip the wine entirely, substitute chicken or beef broth.
Don't substitute the whole milk if you can help it. The fat and natural sugars balance the acidity of the crushed tomatoes in a way low-fat milk won't.
Freeze leftovers for up to 3 months, or store cooled sauce in the fridge for up to 3 days. You may need to add a bit of water or broth when reheating on the stove.
