This is a wonderful sandwich! And the tomato garlic sauce is really a find. I’ll use it in so many ways. All the flavors in this sandwich shine through and go perfectly together. This recipe is definitely a keeper.
These Breakfast Sandwiches Are Life.

Over-the-top, super-indulgently, must-make, weekend brunch LIFE. Sleep in, wake up, pull on sweatshirt, assemble bed head top knot, grab coffee, make sandwich.
We’ve got butter croissants, a tangy tomato butter sauce (more like tomato jam?), salty thick-cut bacon, soft-cooked eggs, and a smash of guacamole to finish it off.
In the last month: I’ve made these for myself, then our team, then for our friend Joe when he stayed with us for a few days, and again during the week to make life a little more manageable. Overkill and I care zero percent. ♡
It is just THE ULTIMATE breakfast sandwich.
So go pick up some croissants and let’s go! It’s time to make some breakfast sammies.

Watch How To Make This Breakfast Sandwich

Ingredients You’ll Need
Breakfast sandwich includes but not limited to:
- Croissant
- Salty bacon (thick-cut, please)
- Egg (SOFT SCRAMBLE because it changed your life too, right?)
- Garlic Butter Tomato Sauce
- Guacamole (or mashed avocado)
I extend all my breakfast sandwich love to any variations of this creation. English muffins. Pepperjack Cheese. Gouda cheese. Roasted red peppers. Magic Green Sauce. Fried eggs with a runny yolk.
How To Make The Best Breakfast Sandwich
Making these sandwiches could not be easier! Here’s what you’re going to do.
- Get your croissants nice and golden with a quick pop in the oven for a minute.
- Cook up your eggs in a skillet over medium-low heat until they’re perfectly soft. Gently swipe your spatula across the pan when the edges of the eggs start to create soft curds. Watch these closely so that you don’t overcook them.
- Build your breakfast sammie! Pile high some crispy bacon, tangy garlic butter sauce, guacamole (obviously), and a slice of pepperjack cheese. To keep it a bit more mild, you could also use a slice of cheddar cheese instead. Holy moly! You’re about to be in actual breakfast heaven with this.

How To Make Eggs For a Breakfast Sandwich
The essential is obviously the soft scramble, which we talked about at length earlier this week. This is no McD’s breakfast sandwich (although, to be fair, I have been known to eat and love a Sausage Biscuit with Egg in moments of weakness). But no, there are no perfectly formed egg disk here.
We’re talking about super creamy, gently cooked, soft scrambled eggs. Life changing.
If scrambled eggs aren’t your thing, you have options. You could make eggs on a sheet pan for a crowd. Cook your eggs fried or sunny side up. Poach it. Your choice!

Variations To Try
Though we really love these breakfast sammies with bacon, garlic butter sauce, guac, and cheese, it’s really a choose-your-own adventure here and there are endless combos that would work well and be very, very delicious!
- Maybe you want to try a waffle or a tortilla wrap instead of a croissant? Love it! Those waffle nooks and crannies are perfect for holding your sammie components. I also love this full-on breakfast burrito!
- Perhaps a layer of crispy fried hashbrowns or potatoes tucked in there? That’s a yes from us!
- Did we hear someone say a little pickled onion topping for tang or hot sauce or some heat? We like the way you roll! Big flavors ahead!

Breakfast Sandwich: Frequently Asked Questions
I mean, you could… but also a buttery toasted croissant here is just TOO GOOD. An English muffin would work great here in a pinch as well.
Magic Green Sauce would also be a REAL WIN here. Salsa. Your favorite hot sauce. Whatever you like to top on your eggs.
A delicious simple arugula or mixed greens salad with vinaigrette would be great here. Also: fruit, juice and/or mimosas, pastries of some kind, and (obviously) lots of coffee.
Just omit the bacon! Maybe even replace with roasted mushrooms!? Yum.
This is more of a fresh, slow weekend morning kind of breakfast sandwich. If you’re looking for something to prep ahead and freeze, take a look at our Meal Prep Breakfast Sandwiches with some easy sheet pan eggs.
Some yummy smoked ham or a sausage patty would be delicious as well! I could even see chorizo patty being an option here too.

This breakfast sandwich looks absolutely delicious! I love the combination of flavors you’ve put together, and the tips for perfecting the eggs are super helpful. Can’t wait to try it out this weekend!
I made a vegan version of this using just egg, vegan bacon, and cheese, and it turned out delicious!!! The garlic butter tomato sauce is divine. I will use it next time I make pizza.
This breakfast sandwich recipe looks amazing! I love the combination of flavors you’ve included. I can’t wait to try adding avocado to mine for some extra creaminess. Thanks for sharing such a delicious and easy recipe!
Do you think these could be made ahead and kept warm in the oven for an hour or so?
Yes, that should work just fine!
would like to know the calorie content of the ultimate breakfast sandwich.
thank you
Absolutely amazing paired with pineapple mimosas 10/10!
Hello. My daughter wants to make your Ultimate Breakfast Sandwich for a 4H Cookoff Contest. We have to have individual nutrition information for each ingredient and total plate. It must follow MyPlate guidelines and less than 750 calories. Do you know the individual amounts for each ingredient: 1 or 1/2 egg, 2 slices bacon, 2tbsp guacamole 1/4 cup tomato sauce, 1 slice cheese?? Also small or large croissants? Any help would be greatly appreciated. Thanks. Crystal
What guacamole recipe do you use for this sandwich?? I know it can be simple, but little changes van make a big difference.
I made this with a few adjustments. I did just regular scrambled eggs (not soft) and I didn’t feel like making the tomato sauce. I looked for tomato chutney at the grocery store but couldn’t find it, so I replaced it with an onion and garlic jam. It was super delish!!!
I will be adding this to my favorite breakfast sandwich,
I believe the most important part of this recipe is getting the garlic butter tomato paste right, I used 2 tablespoons of butter and sprinkled garlic salt over the butter, and added about a 2 tablespoons of tomato paste stirred in a bowl until creamy light red, their is no guidelines to making the perfect garlic butter tomato paste.
My fiance and i always wing it when it comes to making new recipes kinda a little more exciting and adventurous.
This is an awesome recipe! Thanks for sharing!
wow amazing
Wow yummy!
will be cooking this for my wife on mother’s day but plan to use bagels, avo, bacon and eggs
Sounds delicious! Hope she enjoys, Michael!
I can’t wait to try out this recipe. Its quite simple!
This looks amazing, and I can’t wait to make it! I would love to meal prep this. Can you freeze this (minus the avocado) and pop in the microwave when you want to eat it?
Hi, Brittni! We haven’t tried freezing these yet, but we think it should work. Let us know how this goes for you!
Made this last week and making it again tomorrow. Needless to say, it was amazing. So happy I found this recipe. SUCH a great, and versatile, sauce too. I do forgot to add the butter to the sauce and it was still A+. Thank you!!!
