For the Hearty and Flavorful Meat Sauce (Soutzoukakia):

• • 1 pound Ground Beef: Lean ground beef is the classic choice, providing a rich and savory base for the meat sauce. You can also use a blend of ground beef and ground lamb for a more traditional Greek flavor, or substitute ground turkey or chicken for a lighter option. Look for ground beef that is around 85% lean to avoid excessive grease while still retaining flavor.

• • 1 medium Yellow Onion, finely chopped: Yellow onion forms the aromatic foundation of the meat sauce. Finely chopping ensures it cooks down and blends seamlessly into the sauce, adding sweetness and depth of flavor. White onion can also be used, but yellow onion is generally preferred for its milder sweetness.

• • 2 cloves Garlic, minced: Garlic is essential for adding pungent and savory notes to the meat sauce. Freshly minced garlic is always recommended for the best flavor. You can use pre-minced garlic from a jar for convenience, but fresh garlic will provide a more robust aroma and taste.

• • 1 (28 ounce) can Crushed Tomatoes: Crushed tomatoes form the liquid and body of the meat sauce. Use good quality crushed tomatoes for the best flavor. You can also use tomato puree or diced tomatoes (drained and slightly crushed) as alternatives, but crushed tomatoes provide the ideal texture for Pastitsio sauce.

• • 1/2 cup Dry Red Wine (optional, but highly recommended): Dry red wine adds depth, richness, and complexity to the meat sauce. A dry red wine like Cabernet Sauvignon, Merlot, or a Greek red wine like Agiorgitiko works beautifully. If you prefer to omit the wine, you can substitute beef broth or water, but the wine significantly enhances the flavor profile.

• • 1/4 cup Tomato Paste: Tomato paste intensifies the tomato flavor and adds richness and depth to the sauce. It also helps to thicken the sauce slightly.

• • 1 teaspoon Dried Oregano: Dried oregano is a quintessential Greek herb and adds a characteristic Mediterranean flavor to the meat sauce. Use good quality dried oregano for the best aroma.

• • 1/2 teaspoon Ground Cinnamon: Ground cinnamon might seem unusual in a meat sauce, but it’s a key ingredient in Pastitsio, adding a warm, subtle sweetness and a unique aromatic complexity that is distinctly Greek. Don’t skip it!

• • 1/4 teaspoon Ground Allspice: Ground allspice complements the cinnamon and oregano, adding another layer of warm, aromatic spice to the meat sauce. A little goes a long way with allspice, so use it sparingly.

• • 1 Bay Leaf: A bay leaf adds a subtle, herbaceous depth to the sauce as it simmers. Remember to remove it before assembling the Pastitsio.

• • Salt and Black Pepper, to taste: Salt and black pepper are essential for seasoning the meat sauce and enhancing all the flavors. Season generously to taste, starting with about 1 teaspoon of salt and 1/2 teaspoon of black pepper, and then adjust as needed.

• • Olive Oil: Olive oil is the traditional cooking fat in Greek cuisine and is used for sautéing the onion and garlic and browning the ground beef. Use good quality olive oil for the best flavor.

For the Pasta Layer (Base):

• • 1 pound Pastitsio Pasta (or Bucatini): Pastitsio pasta is specifically designed for this dish and is a thick, hollow pasta tube, similar to bucatini but slightly wider. If you can find Pastitsio pasta, it’s the most authentic choice. If not, bucatini is the best substitute. You can also use penne or rigatoni as alternatives, but the traditional hollow tube shape is ideal for Pastitsio.

• • 1/4 cup Grated Kefalotyri Cheese (or Parmesan): Kefalotyri is a hard, salty Greek cheese that is traditionally used in Pastitsio. It adds a sharp, salty flavor to the pasta layer. If you can’t find Kefalotyri, Parmesan cheese is a good substitute, although it will be slightly milder in flavor.

For the Creamy Béchamel Sauce (Veloute):

• • 1/2 cup (1 stick) Unsalted Butter: Butter forms the base of the béchamel sauce, adding richness and flavor. Unsalted butter is preferred so you can control the saltiness of the sauce.

• • 1/2 cup All-Purpose Flour: All-purpose flour is used to thicken the béchamel sauce, creating a smooth and creamy texture.

• • 4 cups Milk, warm: Whole milk is recommended for the richest and creamiest béchamel sauce. 2% milk can also be used, but whole milk provides the best texture and flavor. Warming the milk helps it incorporate smoothly into the roux (butter and flour mixture) without lumps.

• • 2 large Eggs, lightly beaten: Eggs add richness, structure, and a slight custardy texture to the béchamel sauce. Beating them lightly before adding to the sauce helps to prevent them from scrambling.

• • 1/4 cup Grated Kefalotyri Cheese (or Parmesan): Just like in the pasta layer, Kefalotyri (or Parmesan) cheese adds a salty, savory flavor to the béchamel sauce, complementing the other ingredients.

• • Pinch of Ground Nutmeg: A pinch of ground nutmeg is a classic addition to béchamel sauce, adding a warm, subtle spice and aromatic complexity. Freshly grated nutmeg is even better if you have it.

• • Salt and White Pepper, to taste: Salt and white pepper season the béchamel sauce and enhance its flavors. White pepper is traditionally used in béchamel for its milder flavor and to avoid black specks in the white sauce, but black pepper can be used if you prefer. Season to taste.
