- 1/2 cup olive oil

- 1 tablespoon butter
Instructions:
Prepare the Egg Frittata:
- In a mixing bowl, whisk together the eggs and milk until well combined.
- Stir in the chopped spinach (or kale) and shredded mozzarella—season with salt and pepper.
- Pour the mixture into a greased baking dish or oven-safe skillet.
- Bake at 375°F (190°C) for 15-20 minutes or until the eggs are set and slightly golden. Once done, set aside to cool slightly before cutting into sizes that fit your buns.
Make the Basil Pesto:
- In a food processor, combine the basil leaves, garlic, nuts, and Parmesan cheese. Pulse until coarsely chopped.
- While the processor is running, slowly add the olive oil and blend until the mixture becomes a smooth paste—season with salt and pepper. Adjust the consistency with more oil if needed.
Assemble the Sandwich:
- Slice the buns in half and lightly butter each side. Toast them on a skillet or under the broiler until golden brown.
- Spread a generous layer of basil pesto on the bottom halves of each bun.
- Place a slice of mozzarella cheese on top of the pesto.
- Cut the baked egg frittata to fit the buns and place a piece on top of the mozzarella.
- Cap with the top halves of the buns.
Tips for the Perfect Sandwich:
- Freshness Matters: Use fresh basil and high-quality mozzarella for the best flavor.
- Customize Your Frittata: For extra flavor, feel free to add other ingredients like diced bell peppers or onions.
- Serving Suggestion: While best served warm, this sandwich can also be enjoyed at room temperature if you’re on the go.
What to serve with
When it comes to elevating your breakfast or brunch experience with the homemade Starbucks Egg, Pesto & Mozzarella Sandwich, pairing it with complementary sides can transform a simple meal into a feast.
1. Fresh Fruit Salad: A refreshing fruit salad can balance the richness of the egg and pesto sandwich. Opt for seasonal fruits like strawberries, blueberries, and kiwi or go tropical with mango and pineapple chunks. The natural sweetness and acidity of the fruits will complement the savory flavors of the sandwich.
2. Greek Yogurt with Honey and Granola: For a creamier side, serve your sandwich with a bowl of thick Greek yogurt topped with a drizzle of honey and crunchy granola. This combination offers a contrast in textures and flavors, adding a sweet note and a probiotic boost to your morning.
3. Vegetable Hash: A skillet hash made from diced potatoes, onions, bell peppers, and zucchini can be a hearty and colorful side. Seasoned with herbs like thyme and rosemary and cooked until slightly crispy, it adds a comforting element to the meal.
4. Soup: For a cozy brunch, especially during cooler weather, pairing your sandwich with a cup of soup can be very satisfying. Consider light options like tomato basil or a vegetable minestrone that won’t overpower the flavors of the sandwich.
5. Avocado Slices or Guacamole: Adding avocado provides a creamy texture and healthy fats that complement the egg and pesto’s richness. Serve slices of avocado on the side or a small bowl of guacamole for dipping or spreading.
6. Mixed Greens Salad: A simple salad of mixed greens, cherry tomatoes, cucumber, and a light vinaigrette offers a crisp and refreshing side that cuts through the sandwich’s richness. You can also add nuts and seeds for an extra crunch.
7. Smoothies or Fresh Juices: For a drink that doubles as a side, consider blending up a nutritious smoothie or squeezing some fresh juices. Options like an orange carrot ginger juice or a spinach and berry smoothie can complement the meal with their vibrant flavors and additional health benefits.
8. Coffee or Tea: Don’t forget the beverages! A freshly brewed cup of coffee or a selection of teas can perfectly round off the breakfast experience, echoing the Starbucks vibes. Whether it’s a robust dark roast, a creamy latte, or a soothing green tea, the right drink can set the tone for the day ahead.
Ingredients Substitutes
When recreating the Starbucks Egg, Pesto & Mozzarella Sandwich at home, you might need to substitute various ingredients due to dietary restrictions, allergies, or simply availability.
1. Ciabatta Bread
Substitute: Any artisan bread such as focaccia, sourdough, or a hearty whole grain loaf can be an excellent alternative. For a low-carb option, consider using a lettuce wrap or a low-carb keto bread.
2. Basil Pesto
- Dairy-Free/Vegan Substitute: Look for vegan pesto in stores or make your own by replacing Parmesan cheese with nutritional yeast or vegan Parmesan.
- Nut-Free Substitute: If you’re allergic to nuts, make a homemade pesto and substitute sunflower or pumpkin seeds for pine nuts.
- Store-Bought vs. Homemade: Homemade pesto is fresher and can be customized, but if in a pinch, a quality store-bought pesto will work.
3. Mozzarella Cheese
- Dairy-Free/Vegan Substitute: Use a dairy-free mozzarella cheese alternative found in most grocery stores. Some brands offer excellent melting properties suitable for sandwiches.
- Substitute Cheese: If you’re just looking for a different flavor profile but still want cheese, consider provolone for its mild flavor or a smoked gouda for a more pronounced taste.
4. Eggs
- Egg Substitute for Allergies: Scrambled tofu is a great vegan alternative that can mimic the texture of eggs when turmeric and nutritional yeast are added for color and flavor.
- Cholesterol-Free Substitute: For an omelet-like layer, use an egg substitute product or a chickpea flour batter (mixed with water, turmeric for color, salt, and a pinch of black salt for an eggy sulfur flavor).
5. Spinach
Substitute: Arugula can be an excellent alternative, giving a peppery flavor or kale for a heartier, chewier texture. Both offer a similar nutritional profile and work well with the other ingredients.
6. Salt and Pepper
Seasoning Adjustments: While salt and pepper are basic seasonings, consider a dash of paprika or garlic powder for a subtle change in flavor profile without straying too far from the original taste.
7. Butter (for Toasting the Bread)
- Dairy-Free/Vegan Substitute: For a dairy-free version, use plant-based butter or a light brushing of olive oil on the bread before toasting.
- For a Healthier Option, Opt for spray oil or simply toast the bread without butter for a lower-calorie option.

There you have it—a homemade Starbucks Egg, Pesto & Mozzarella Sandwich that is sure to impress.
