For the Foundation:

• 4 Croissants: Ah, the croissant. This isn’t your average bread choice, and that’s precisely what makes this sandwich so special. Opt for good quality, all-butter croissants if possible. Their inherent richness and flaky texture are crucial to the overall experience. Day-old croissants work perfectly, as toasting will revive their crispness. Avoid overly sweet or filled croissants; you want the buttery flavor to complement, not compete with, the other ingredients. If you’re feeling ambitious, you could even bake your own croissants, but store-bought, bakery-fresh croissants are an excellent and convenient choice. Think about the size too – medium to large croissants will hold the fillings best without becoming unwieldy to eat.

The Protein Powerhouse:

• 8 Large Eggs: Eggs are the heart of any great breakfast sandwich, and for this recipe, soft scrambled is the key. We’re not talking dry, rubbery scrambled eggs here. We want creamy, tender, almost custardy eggs that melt in your mouth. Using fresh, high-quality eggs will contribute to a richer flavor and better texture. Two eggs per sandwich provide a generous portion of protein and contribute to the overall satisfying nature of the meal. If you prefer a richer egg flavor, consider using pasture-raised eggs.
• 4 Slices Cooked Bacon: Bacon. Need we say more? The smoky, salty crunch of bacon is a classic breakfast staple and a perfect partner for eggs. Choose your favorite type of bacon – thick-cut for extra chewiness and flavor, or regular cut if you prefer a crispier texture. Applewood smoked bacon, hickory smoked bacon, or even peppered bacon could add interesting flavor variations. Make sure the bacon is cooked to your preferred level of crispness before assembling the sandwiches. You can cook bacon in the oven, on the stovetop, or even in the microwave for speed.

The Flavor Enhancers:

• 1/2 Cup Guacamole: Guacamole in a breakfast sandwich? Absolutely! This is where the “ultimate” part really kicks in. The creamy, cool guacamole adds a layer of freshness and vibrant flavor that cuts through the richness of the other ingredients. Homemade guacamole is always best, allowing you to control the spice level and freshness. Use ripe avocados, lime juice, cilantro, red onion, and a pinch of salt for a classic guacamole. If you’re short on time, high-quality store-bought guacamole will also work well, but try to find one that is freshly made and not overly processed.
• 1/2 Cup Basic Garlic Butter Tomato Sauce: Tomato sauce in a breakfast sandwich might sound a bit unconventional, but trust us, it works wonders. This isn’t just any tomato sauce; it’s a chunky, garlic butter infused version that adds a burst of savory, slightly sweet, and aromatic flavor. Homemade tomato sauce is recommended for the best flavor, allowing you to control the ingredients and chunkiness. Use good quality canned tomatoes (diced or crushed), garlic, butter, and herbs like basil or oregano. Simmering the sauce briefly will meld the flavors together beautifully. If you’re using store-bought sauce, look for a chunky marinara or tomato basil sauce and add a touch of garlic butter to enhance the flavor.
• 4 Slices Pepper Jack Cheese: The “kinda spicy” element comes from the pepper jack cheese. This cheese adds a delightful warmth and a subtle kick that complements the other flavors without being overpowering. Pepper jack cheese melts beautifully, creating a gooey, cheesy layer in the sandwich. If you prefer less spice, you can substitute with Monterey Jack cheese or mild cheddar, but the pepper jack really elevates the flavor profile. Ensure the cheese slices are large enough to generously cover the eggs within the croissant.
