Omelette with crispy bacon, red onion, and toast
I recently had this experience: I was starving and found some stray bacon bits at the bottom of the fridge from an old meal, along with a small, lonely red onion. When you're in a hurry but don't want to eat something completely dry, you end up with improvised combinations like this one—and that's how I came up with this omelet that really deserves to be shared. I admit, the first time I added the onion too early and it got too soft, but I learned: it just needs to touch the pan, not turn into jam.
Quick info (this is how it goes for me):
Preparation time: 7-8 minutes
Cooking time: about 5 minutes
Servings: 1 hearty serving (or 2 smaller ones, if you're patient enough to share)
Level: for anyone who knows how to crack eggs and handle a pan
Ingredients + their roles (nothing is unnecessary)
2 eggs – the base, obviously, they provide substance and hold everything together
4-5 bacon bits – for that serious salty flavor and texture (I don't know why, but it doesn't turn out the same with regular bacon)
1 small red onion – adds freshness and a bit of sweetness, cutting through the fat
1 pinch of salt – just enough to avoid blandness, be careful with how salty the bacon bits are
1 teaspoon of classic mustard – brings the eggs into a more interesting territory, don't let them be just eggs
1 teaspoon of milk – makes the omelet fluffier, not strictly necessary, but I always add it
1 slice of rye toast – crunchy crumbs, so everything doesn't end up soft
2-3 drops of olive oil – just enough to prevent sticking
Preparation method, briefly and honestly:
1. Crack the eggs into a bowl—any bowl, it doesn't need to be very big. Add the salt, mustard, and milk. Beat them with a fork; I don't bother with a whisk for an omelet. The idea is to create a homogeneous mixture, but don't whip it too much. If you incorporate too much air, you won't like the texture; it gets a bit rubbery.
2. Peel the onion, slice it lengthwise into thin strips, but not too thin. If you cut it too thin, it will melt away and you won’t feel it in the end. If it's too thick, it will remain hard. I cut mine to about the thickness of a credit card, that’s how I like it.
3. Cut the slice of toast into four, about the size of crouton pieces. I tried putting it in whole, but didn’t like that it didn’t toast evenly.
4. Place the pan (non-stick if you have one, otherwise it will be a struggle at the end) on medium heat. Pour in 2-3 drops of olive oil, just enough to brush it with a pastry brush or a napkin. No need for a puddle.
5. Toss the onion into the pan, then the bacon bits and the bread pieces. You don't need to sauté them, just warm them up until you can smell the raw onion—max 30 seconds. It's important not to let the onion cook completely, or you lose the texture contrast.
6. Pour the beaten eggs over what's in the pan, tilt the pan a bit to cover the bottom, and don’t start mixing like you would for scrambled eggs. Let it sit for about 1 minute to set on the bottom. I check gently with a wooden spatula on the edge—if it’s released, carefully flip it. It doesn’t have to look like a perfect pancake; it’s actually better when it’s a bit messy.
7. Let it cook for another 40-50 seconds on the other side, no more. If you like it softer or a bit runny, take it off sooner. If you want it fully cooked, aim for a minute.
8. Flip it onto a plate—don’t wait too long, or it will harden. I like to serve it with some halved cherry tomatoes on the side, and if I'm in the mood, I also drink a glass of cold yogurt. It pairs perfectly.
Why I make this recipe often:
Honestly, because it takes 10 minutes and doesn’t leave you hungry like a plain omelet. Plus, if you have leftover bacon bits, it’s a shame to just eat them on bread—you give them a chance to shine in a different way. I love that it has everything you need in one pan: protein, fat, some fiber from the rye, and the freshness from the onion. It’s the kind of breakfast or dinner I make when I don’t feel like spending time in the kitchen but don’t want to order something either.
Tips, variations, and serving ideas
Useful tips (and what I got wrong):
- Don’t over-salt from the start. Bacon bits are usually salty already. I’ve ruined an omelet just by adding salt with my eyes closed.
- The onion shouldn’t be sautéed. If you leave it too long, you lose crunch and flavor. In two attempts, I turned it into “jam” and it lost all its charm.
- A pan that’s too hot burns the bread. Medium heat, don’t rush. If you have induction, stay around level 6 out of 10.
- If you want to flip the omelet and it won’t release, cover it for a minute—it will release on its own.
Ingredient substitutions (if you have special needs or just don’t have everything on hand):
- Rye toast: you can use any other denser old bread, but avoid fluffy white bread. If you want gluten-free, use gluten-free croutons, same technique.
- Bacon bits: if you don’t have them, you can try crispy fried bacon, though it won’t have the same flavor. Even some pieces of smoked pork belly work, but they’re not as filling.
- Mustard: if you don’t like it or don’t have it, you can skip it, but it really helps with flavor. You could substitute a bit of grated horseradish for a slightly spicy note.
- Milk: any type of milk works, including plant-based (almond, oat), if necessary. It also works without it, but the omelet turns out denser.
Variations and other ideas (based on mood or restrictions):
- You can add a bit of grated cheese, but not too much, or it will melt into the eggs and you won’t taste anything else.
- Instead of red onion, you can use thinly sliced leeks or green onions. Each has a different taste, but red onion is sweeter and doesn’t bother you if left slightly raw.
- If you're on a diet, reduce the bacon bits by half and add more vegetables—I’ve sometimes added zucchini or small diced bell peppers.
- For a completely vegan option, the omelet won’t work—but you can make a “frittata” with just vegetables and plant-based milk without bacon bits.
Serving (what goes best with it):
- Cherry tomatoes or cucumber slices—fresh and cuts through the heaviness.
- A spoonful of cold yogurt, if you want it to feel less greasy.
- Black tea or strong coffee on the side—it works in the morning, less so at dinner (because you won’t sleep).
- You can make a green salad, and it’s just what you need for a complete meal.
Frequently asked questions (I’ve received these or heard them from acquaintances)
1. Can I use other types of meat instead of bacon bits?
Yes, bacon or even smoked chicken breast works, but it won’t have that crispy fat that bacon bits bring. Smoked ham adds a different, softer flavor. Personally, I think bacon bits are the best because they don’t dry out the omelet and add flavor.
2. What do I do if I don’t have a non-stick pan?
Grease a regular pan with a thin layer of lard or oil and heat it well before adding the ingredients. The idea is to prevent the omelet from sticking; otherwise, it’s hard to flip. If it still sticks, use a wide spatula and scrape patiently.
3. I have an egg allergy. What alternative can I try?
You can make a vegan “omelet” with chickpea flour, water, and spices (turmeric, salt), but don’t expect it to taste the same. You can add the same plant-based bacon bits (if you find something based on smoked soy) and the rest of the ingredients the same.
4. Can it be made without bread?
Yes, just don’t add the bread to the pan. The omelet turns out “cleaner,” but you lose that crunchy texture with every bite. You could add some seeds (pumpkin or sunflower) if you want it to be more interesting.
5. Can it be made in the oven or just on the stove?
I always make it on the stove; it’s quick and doesn’t dry out. You can make it in a small oven dish, but don’t leave it too long, or it becomes too dry. It should be ready in a maximum of 10 minutes at 180°C; check to make sure the bread doesn’t burn on top.
Nutritional values (approximate, per serving):
Let’s not hide behind our fingers—it’s not “light” food, but it’s not a calorie bomb if you don’t overdo it with the bacon bits. I estimate about 370-400 kcal per serving, with all the ingredients listed above.
Macronutrients: about 18-20g protein (from eggs, bread, and bacon bits), around 28g fat (about 15g saturated, the rest better), 14-16g carbohydrates, 2-3g fiber if you have rye or whole grain bread. The salt can vary a lot, depending on how much you add and how salty the bacon bits are.
Why is it okay? Because it has a lot of protein, it keeps you full. Bacon bits aren’t the healthiest thing if you eat them daily, but in an omelet, it’s not a tragedy. It’s not something I would eat for every breakfast, but it’s much healthier than a store-bought sandwich with cold cuts. The milk and onion slightly lighten the egg and help with digestion.
How to store and reheat
It’s not food that keeps well overnight, but if you’ve made too much (which rarely happens to me), put the leftover omelet in a container with a lid in the fridge for up to 24 hours. When you want to eat it, reheat it in a pan on low heat, covered with a lid, or in the microwave for about 40 seconds—but no more, or it becomes rubbery. It’s definitely better fresh, but it’s acceptable the next day if you don’t feel like cooking again.
That’s how I’ve made it every time I wanted an omelet with a little extra “something.” If you have patience, believe me: you’ll only regret it if you forget the omelet on the heat or add too much salt. Other than that, you can’t go wrong with it.
Ingredients: 2 eggs, 4-5 bacon strips, 1 small red onion, 1 teaspoon of salt, 1 teaspoon of mustard, 1 teaspoon of milk, 1 slice of rye toast, 2-3 drops of olive oil
