Let’s be honest, mornings can be a challenge. I am definitely not a morning person. No matter how much I try to embrace the early hours, getting myself fully awake and motivated before my first cup of coffee is an uphill battle. My mornings typically unfold with me getting dressed, then immediately heading for that essential first cup of coffee. The thought of preparing a substantial breakfast often feels like an insurmountable task at that hour. I usually find myself lingering over my coffee, pondering what to eat, or more accurately, what I can quickly grab, because a full-on cooking session is simply not on the agenda.
This struggle stems from a combination of factors: a complete lack of morning motivation to cook anything elaborate, and a strong desire to simply get my day started without any culinary detours. It’s ironic, really, because I genuinely love breakfast foods. The savory delights of bacon, sausage, eggs, and crispy hash browns are some of my favorite comfort foods. However, these hearty meals often make their appearance much later in the day – typically for brunch or what I affectionately call “brinner” (breakfast for dinner). In fact, if given the choice, I’d much rather enjoy dinner for breakfast!
I recall a memorable trip to Brooklyn in December where a friend and I decided on dim sum for breakfast. It was an absolute revelation and, hands down, the best breakfast I had enjoyed in a long time. The variety, the flavors, the communal experience – it was everything a breakfast should be, but rarely is for me. Similarly, if I order Chinese food for dinner, you can bet I’ll be enjoying the leftovers the very next morning. Occasionally, I even indulge in sushi for breakfast. It leads me to wonder, what do you even call dinner for breakfast? Dinfast? Brinner seems more fitting for those intentional savory breakfast experiences.
So, when friends suggest meeting up in the morning, my immediate thought is always brunch. Brunch offers the best of both worlds, often featuring dishes that blur the lines between breakfast and dinner. How can anyone resist the pure joy of chicken and waffles for brunch? It’s a meal that truly satisfies. And speaking of brunch items that are perfectly acceptable for dinner, or any time of day for that matter, quiche stands out as a versatile and incredibly delicious option. For many years, I wasn’t particularly fond of quiche, but somewhere along the journey of adulthood, my palate evolved, and now I find myself craving its custardy goodness quite often.
One evening, a truly brilliant idea struck me: why not combine the comforting, rich flavors of French onion soup with the elegant structure of a quiche? And thus, the concept of French Onion Quiche was born. It captures the essence of caramelized onions and Gruyere cheese, delivering that deep umami flavor profile we all love, but in a convenient, sliceable form. The true beauty of making quiche, especially for someone who struggles with mornings, is its incredible make-ahead potential. You can bake it completely the day before, eliminating any morning rush or decision-making. Simply reheat and enjoy a gourmet breakfast with minimal effort.
