Knockout Breakfast Sandwich mixes fluffy scrambled eggs, crunchy bacon, creamy guacamole, tomato sauce with a kick, and melted pepper jack cheese on a buttery, flaky croissant. It's done in just 15 minutes and gives you the perfect mix of textures and tastes in every mouthful.
I came up with this sandwich when I needed something wow-worthy but easy for hosting friends on weekends. After trying different bacon types and butter blends, this version became our go-to favorite. My hubby says they're the tastiest sandwiches he's ever had, and now everyone who visits asks me to make them.
Key Ingredients and Smart Picking Advice
- Croissants: Pick the ones made with real butter for the yummiest flavor and best bite.
- Bacon: Go for the thick slices to get that hearty, meaty crunch.
- Eggs: Choose farm-fresh organic ones for the most vibrant yellow and fullest flavor.
- Garlic Butter Tomato Sauce: Adds that special savory depth you'll love.
- Guacamole: Brings smooth, rich texture and cuts through the other strong flavors.
- Pepper Jack: Gives a little heat kick and nice pop of color.
I've noticed that a tiny bit of chicken bouillon powder really makes these taste like something from your favorite breakfast spot. Don't have any? Try mushroom powder instead – it adds that same deep flavor boost without changing how everything tastes together.
Step-By-Step Cooking Guide
- Step 1: Get Those Croissants Just Right
- Cut croissants halfway through so they open like a book. Put them open-faced on a baking tray and warm at 350°F until the edges turn golden but the inside stays soft.
- Step 2: Make Dreamy Eggs
- Lightly beat eggs until just mixed. Cook them in a buttered non-stick pan on medium-low heat, gently pushing them around to form soft lumps. Take them off while they still look a bit wet.
- Step 3: Nail the Bacon
- Put bacon in a cold pan, then turn to medium heat. Let it cook slowly until it's crispy and brown. Put on paper towels to soak up extra grease and keep it crunchy.
- Step 4: Stack Your Masterpiece
- Spread tomato sauce on the bottom half, then add eggs, bacon, and guacamole. Put cheese on the top half so the warmth from everything else makes it start to melt.
- Step 5: Finish It Off
- Gently close the sandwich without squishing it. Cut across the middle for a pretty look and eat right away while everything's at the perfect temperature.

When I first tried making these sandwiches, I learned how important it is to stack everything right. I started by piling all the fillings on one side, which made the croissants soggy and the flavors uneven. Now I carefully place each ingredient, making sure you get all the tastes and textures in every bite.
Great Food Combos
These go really well with some fresh fruit on the side to balance out the richness. Strawberries or orange slices work great. For fancy brunches, add some bubbly mimosas. In winter, a strong coffee with chocolate hints really brings out all the flavors.

Mix It Up
Try using waffles instead for a sweet-salty combo or brioche buns for something rich but not flaky. Add some hash browns for extra crunch. Vegetarians can swap bacon for portobello mushrooms seasoned with smoked paprika to get that same deep flavor satisfaction.
Sauce Ideas
You could try an herb-avocado sauce with lime for something fresh in summer, spicy chipotle sauce for some heat, or sweet maple butter that bridges breakfast and lunch flavors. Each one totally changes the sandwich while keeping the basic idea intact.
Planning Ahead
You can cook the bacon earlier and warm it up while toasting croissants. Make your sauce a few days before and just heat it when needed. When having friends over, set up all the ingredients so everyone can build their own sandwich just how they like it.

Smart Cook Tricks
- Toast your croissants right before putting sandwiches together for the best crunch
- Take eggs off the heat while they're still a bit runny since they'll keep cooking
- Make sure bacon is well-drained so it stays crispy
- Heat up your guacamole slightly before spreading it
- Make each sandwich one at a time instead of doing them all at once
Frequently Asked Questions
- → Can I make parts of this sandwich earlier?
- Of course! Fry the bacon up to 3 days ahead and store in the fridge (warm it briefly later). You can also prepare the tomato garlic sauce a week in advance and whip up the guacamole the night before (just add lime juice and cover tightly). For the eggs and toasted croissants, make those fresh for the best taste.
- → What’s the secret to soft scrambled eggs?
- Beat the eggs gently with a pinch of salt. Heat butter in a non-stick pan over low heat, pour in the eggs, and push them to the center slowly with a spatula as they cook. Stop when slightly wet—they’ll finish cooking from the heat of the pan. Don’t overdo it or they’ll turn rubbery.
- → What can I use instead of pepperjack cheese?
- Not a fan of spicy? Try mild options like provolone, havarti, cheddar, or monterey jack. For a little zing without the heat, Swiss or gouda work great. Go for a cheese that melts easily to keep that satisfying gooeyness.
- → How do I make the garlic tomato sauce?
- Simple! Sauté 2-3 minced garlic cloves in butter until fragrant, mix in 1 cup crushed tomatoes, and sprinkle with salt, pepper, and dried herbs. Let it simmer for 5-10 minutes to thicken. Short on time? Use jarred marinara with garlic and butter stirred in.
- → Can these sandwiches feed a group?
- Absolutely! Make it a fun brunch station. Toast croissants on baking sheets, cook a big batch of eggs (slightly underdone), and lay out toppings for self-serve sandwiches. Set up warming trays for ingredients to stay at the right temp—works well for 12-16 people, no problem!
