Why I Like This Recipe

Didn’t even know I needed this until I made it. Now it’s in a jar in my fridge at all times. I use it on eggs, wraps, even fries.

Ingredients

• ½ cup mayonnaise
• 2 tbsp yellow mustard
• 1 tbsp lemon juice
• 1 tbsp steak sauce
• 1 tsp fresh dill (or ½ tsp dried)
• ½ tsp black pepper
• ¼ tsp salt

How To Make Breakfast Sauce DIY 

• Mix the sauce: In a small bowl, add everything — mayo, mustard, lemon juice, steak sauce, dill, salt, pepper. Doesn’t need to be exact.
• Whisk it all together: Stir until smooth and creamy. Taste. Tweak. Add more mustard if you like it wild.
• Store or use immediately: I usually eat it right away, let’s be honest. But you can chill it in the fridge for up to a week.

Tips for Success

• Don’t skip the dill. It’s tiny, but it shows up.
• Steak sauce adds depth — swap with Worcestershire + sugar if needed.
• Want it spicier? Throw in a dash of hot sauce or cayenne.
• Store in a small jar so it’s grab-and-go in the morning.

Storage and Reheating

• Fridge: Airtight container or jar. Lasts 5–7 days.
• Freezer: Nope. The mayo will separate. Just don’t.
• Reheat: Nope again. It’s a cold sauce. Spread it, dip it, move on.

Frequently Asked Questions

• Can I use light mayo?
  Sure, it’ll work — just won’t be quite as creamy. Still good though.
• What if I don’t have steak sauce?
  Worcestershire sauce with a pinch of sugar gets close enough.
• How much sauce does this make?
  About 1 cup — enough for 6 to 8 sandwiches depending how generous you are.
• Can I make it vegan?
  Yep. Use vegan mayo and check that your steak sauce is plant-based.
• Is this the same as Big Mac sauce?
  Nah. This has more zing, more brightness — definitely its own thing.

Common Mistakes and How to Dodge Them

• Too much mustard: It can overpower fast. Start small and add more to taste.
• Skipping the lemon juice: It wakes everything up — don’t leave it out unless you’re absolutely out.
• Not mixing enough: If it’s not smooth, keep whisking. It’ll come together.
• Using dried dill and forgetting to adjust: If you’re using dried, go lighter. It’s more concentrated than fresh.
• Thinking it’s just for breakfast: Wrong. Burgers, wraps, fries — this sauce is multitasking.
