Classic Baked Beef Lasagna with Rich Cheese Sauce

Building a sturdy Classic Baked Beef Lasagna with Rich Cheese Sauce requires patience and a heavy pot. The ground beef simmers for up to 2 hours to develop a tender Ragu. A blanket of smooth Cheese Sauce tops each tier of pasta before a 25-minute trip to a 350°F (180°C) oven.

The Ragu

Begin the Ragu by heating olive oil in a large pot over medium heat. Toss in the chopped onion, finely diced carrot, finely diced celery, and minced garlic. Cook these aromatics for ten minutes over moderate heat until they soften and release their natural sugars. Avoid browning the vegetables to maintain a sweet flavor base. Add the ground beef and use your spoon to break the meat apart, cooking until every section turns completely brown. Mixing ground pork with the beef is another option that balances tenderness with a strong beefy flavor.

Add the crushed tomatoes, tomato paste, dry red wine, crumbled bouillon cubes, bay leaves, thyme, oregano, and Worcestershire sauce. If you prefer, non-alcoholic red wine or beef broth can replace the dry red wine. Lower the stove setting until the liquid barely simmers with tiny surface breaks. Cover the pot tightly. The closed environment tenderizes the meat during the 1.5 to 2 hours of cooking.

Check the liquid level occasionally if you use a lighter pot instead of a heavy one. You might need to stir in a splash of water so the Ragu does not dry out. Remove the lid for the final thirty minutes to reduce the liquid. Economical canned tomatoes sometimes carry an acidic edge. Taste the cooked mixture and stir in one to two teaspoons of sugar if the acidity requires balancing.

The Cheese Sauce

Warm the milk in a separate container before you add it to the roux. Warm liquid helps the sauce thicken faster. Melt the butter in a second large pot and whisk in the flour. Stir the mixture continuously for one minute. Pour about one cup of the warm milk into the cooked flour mixture gradually. This slow addition keeps lumps from forming.

Add the rest of the milk once the flour dissolves into a smooth paste. Increase the burner to medium-high and stir for five to eight minutes until the liquid coats the back of your spoon. Take the pot off the heat.

Grating a solid block of cheese guarantees a smooth finish for your Cheese Sauce. Packaged pre-shredded options are treated to keep the shreds from sticking together, and those additions will make your melted liquid grainy. Stick to blocks of cheddar, colby, Monterey Jack, or gruyere for a seamless melt. Fold your chosen cheese into the pot alongside a pinch of freshly ground nutmeg, salt, and pepper. Keep stirring until no solid pieces remain. If the resulting mixture feels too tight, thin it with a splash of water or milk. The final liquid must be loose enough to pour easily from your spoon, similar to heavy cream.

Choosing the pasta

Fresh lasagna sheets meld closely with the fillings and stay flat during baking without buckling into wavy shapes. You can use instant dried pasta sheets instead. Make sure your Ragu retains enough liquid if you choose instant dried sheets. A dry meat base prevents the pasta from hydrating fully in the oven. Add a drop of oil to the water if you boil traditional dried sheets so they do not stick together.

Layering the pan

Smear a thin scrape of the meat mixture directly on the bottom of the 13 x 9 x 2.5-inch (33 x 22 x 7 cm) pan. This base prevents the bottom pasta sheets from sliding. Cut or break the pasta to fit the exact dimensions of your baking dish.

Spoon two and a half cups of the meat mixture over the pasta. Drizzle one cup of the white Cheese Sauce evenly over the meat. Alternate the direction of the pasta sheets by ninety degrees on each new layer. The crossing pattern helps the assembled dish hold its shape when you slice it later.

Repeat the sequence of pasta, meat, and white sauce until you have four tiers of pasta in total. Pour all of the remaining white Cheese Sauce across the top. Scatter the shredded mozzarella evenly over the surface. Mozzarella provides excellent melting qualities for the topping without becoming greasy.

Resting and storage

Bake the dish for 25 minutes until the cheese on top turns lightly browned and the edges actively simmer. The baked dish needs five to ten minutes of resting time on the counter before you cut into it. The brief pause allows the internal layers to set. Garnish the cut portions with finely chopped basil or parsley right before eating.

The fully assembled and baked pan freezes perfectly for later use. Add about a quarter cup of extra water when reheating the Ragu if you make the meat sauce ahead of time by itself. The extra moisture restores the correct consistency.
