Secret Ingredient Fully Loaded Egg Croissant Sandwich

This secret ingredient egg croissant sandwich with fluffy scrambled eggs and rich toppings is the ultimate breakfast and brunch dish you didn’t know you needed!

Calling all croissant and egg lovers, this sandwich is a loaded and flavor-packed sandwich that is perfect for anyone who needs a little extra energy for the day.

It is extremely filling and full of protein; not your typical, quick breakfast, but great to make once in a while. This sandwich includes a variety of fillings, including a bit of a secret ingredient and one of our favorite toppings in the world: caramelized onions.

Although cooking caramelized onions is time-consuming, I usually batch-cooked them so that we have some for later meals.

This breakfast (in our case, brunch) sandwich includes scrambled eggs, caramelized onions, American cheese, bacon, chives, avocado, butter and a bit of one secret ingredient (revealed below).

A cast iron skillet is good for this recipe, but I used my favorite skillet, a Kitchen Kraft 10-inch wide pan to caramelize two of our own home grown onions. The greater the surface area, the better for caramelization.

Egg Croissant Sandwich

Recipe for 2, with total cook time about an hour.

For caramelized onions:

2 large yellow onions, thinly sliced

2 tbsp. unsalted butter

For eggs and sandwiches:

3 large eggs

3 tbsp. milk (any fat %)

2 tsp. unsalted butter

2 large croissants, toasted and sliced in half horizontally

2 slices American or cheddar cheese

2 tbsp. chives, diced, plus more for garnish

1 small avocado, sliced

2 strips cooked bacon

1 to 2 tbsp. of secret ingredient (see below)

Note: Salt and pepper to taste. I never salt food, but bacon brings out enough salty taste.


To caramelize the onions, melt butter into a pan over medium heat. Add onions in three batches, cooking the first batch for 2 min while stirring, and then repeating the process for the second and third batch.

Continue to cook onions for 40-45 min, stirring every few minutes to maintain an even color throughout the onions. Adjust heat as needed. If the bottom of the pan is starting to char, add a bit of water as needed to deglaze the pan. Once cooked, set aside.

To make the eggs, beat the eggs and milk together. Stir in the secret ingredient: Zesty Italian Dressing for a mild, but tasty kick.

In a frying pan over low-medium heat, melt the butter. Add in the egg mixture and slowly stir until egg curdles form. Continue to stir until the eggs are slightly set and wet. Add the chives at the end.

Add the hot eggs onto both halves of the croissants and place the cheese on top so that it melts. Top with avocado, bacon, and caramelized onions. Optional: wrap in sandwich paper and slice to enjoy!

Dodie complemented our meal with a small side of blueberries and banana slices. Yum!

Zesty Italian Dressing is easy to make

BONUS: Homemade Zesty Italian Dressing


  • 1/4 cup extra virgin olive oil
  • 3-4 TBSP white wine vinegar
  • 1/2-1 TBSP Italian Seasoning Blend (I use HEB’s Hill Country Faire Blend)
  • 1/2 TBSP garlic powder
  • 1/4 tsp salt
  • freshly ground black pepper to taste


  • 1-2 tsp fresh parsley
  • 1 clove garlic (smashed + minced)
  • 1/8 tsp crushed red pepper flakes


  1. Whisk all ingredients together and allow to sit. Giving the dressing some time to mesh and mingle will not only infuse flavor into the oil/vinegar but also soften the dry herbs and seasoning.
  2. This dressing will keep in your fridge for about a week so make extra to drizzle over a week’s worth of salads!

Recipe Notes

Feel free to adjust oil-to-vinegar ration to taste. The above measurements are my favorite in a vinaigrette. 1 parts vinegar to 3 parts oil is a bit more conventional if desired.


A Special Message From Dodie Dennis (Retired RN)

With 40 years experience as a licensed Registered Nurse on a cruise line, a Colorado ski resort, and in Phoenix, AZ, I did everything from Operating Room to Immunology to all levels of Newborn care.

Among my favorite jobs was teaching childbirth and nutrition classes. For the most part, I believe whole foods trump supplements. And eating a nutritious diet loaded with veggies, grass-fed meat, and plenty of good fats is the starting point. You certainly cannot supplement your way out of poor dietary choices. However, even with the best diet, there may be a few gaps that we might want to fill to “supplement” a solid diet.

For example, Omega-3 fatty acids are vitally important to our health. Our Omega-3 to Omega-6 ratio should be 1:1 or 1:2. Sadly, the average person’s is more like 1:20. Not only are we not getting enough Omega-3 from sources like grass-fed meats and fish/seafood, we’re also over consuming Omega 6 (e.g. vegetable oils, excessive nut consumption) – a double whammy.

Personally, Jack and I don’t eat enough fish to get adequate Omega-3 due to concerns about toxins, mercury, etc. That’s why we welcome a new sponsor to “supplement” with Green Pasture Fermented Cod Liver Oil (FCLO).

Welcome Green Pasture Products to CleverJourneys

I use the word “supplement” loosely here, since FCLO is really a whole food. Not only that, but it’s also a traditional food with a long history of use. Quite the opposite of highly processed fish oils.

Green Pasture’s website

Fermented Cod Liver Oil is simply cod livers fermented naturally to extract the oils. The cold-processing method maintains all the fat soluble vitamins. Most fish oils on the market are heat processed. What’s worse is that they’re then bleached and deodorized, and since most of the vitamins have been removed or destroyed, synthetic vitamins are added back in.

FCLO contains more than Omega 3s. It’s also a great source of Vitamin A and Vitamin D, and contains small amounts of Vitamin K2, Vitamin E, and various other quinones.

If you want to try out the amazing benefits of Fermented Cod Liver Oil, or maybe your current supply is running low, we highly recommend Green Pasture.

They are the only company to supply naturally fermented cod liver oil that we are aware of (and the one recommended most highly by the Weston Price Foundation).

Check out Green Pasture’s website now and tell them CleverJourneys sent you.

In addition to Fermented Cod Liver oil, Green Pasture also sells other products like high vitamin butter oil, coconut oil, and coconut ghee.

Jack likes Green Pasture because they are an American business that share the same patriotic values we do.
