Greek Chicken, Tzatziki, And Yellow Cake Meal Prep

Pro tips

• Marinate the chicken for at least 2 hours (or overnight) so the Greek seasonings fully penetrate the meat.
• Cream the softened butter and sugar until light and fluffy before adding eggs to ensure a tender, even crumb in the yellow cake.
• Let the yellow cake layers cool completely before stacking to prevent frosting from melting or layers from sliding.
• Make tzatziki 1–2 days ahead so the flavors meld; store in an airtight container and stir before serving.

Substitutions

• Greek yogurt → sour cream (in tzatziki, use 1:1 ratio for a slightly tangier sauce)
• All-purpose flour → cake flour (use 2¼ cups for a more delicate texture)
• Sour cream → Greek yogurt (in cake, use equal parts; may slightly reduce milk)
• Unsalted butter → salted butter (omit the ½ tsp salt from the cake recipe)

Storage & make-ahead

Store marinated chicken and tzatziki in separate airtight containers in the refrigerator for up to 4 days. Yellow cake layers keep wrapped at room temperature for 2 days or refrigerated for up to 5 days.

How long does marinated Greek chicken keep in the fridge?

Marinated Greek chicken stays fresh for 3–4 days in an airtight container. Store the tzatziki separately and combine just before eating.

Can I bake the yellow cake layers ahead of time?

Yes, bake the layers up to 2 days in advance. Cool completely, wrap each layer in plastic wrap, and store at room temperature or refrigerate.

What is tzatziki made from?

Tzatziki is a Greek yogurt-based sauce with cucumber, garlic, dill, and olive oil. It pairs with the marinated chicken as a cooling condiment.

Can I scale this recipe for more servings?

Yes. Double or triple the chicken marinade and tzatziki proportionally. For the cake, bake multiple batches or use a larger pan and adjust baking time.

What makes this meal prep efficient?

All components—marinated chicken, sauce, and cake—are made in one session and store separately, letting you assemble meals throughout the week.
