Slice each peeled egg in half lengthwise with one clean, confident cut. Use a small spoon to pop the yolks out cleanly into your mixing bowl. Arrange the whites neatly on your serving platter, hollow side up.
Into the bowl with the yolks, add:
⅓ cup mayonnaise
3 tbsp sour cream
1½ tsp Dijon mustard
1 tsp yellow mustard
1 tbsp sweet pickle relish
1 tsp fresh lemon juice
½ tsp smoked paprika
¼ tsp garlic powder
¼ tsp onion powder
Salt, pepper, and a dash of hot sauce
First, mash the yolks thoroughly with a fork until they resemble fine, dry crumbs with no large lumps remaining. Then transfer everything to a food processor and blend on high for 30 to 45 seconds until the filling is completely smooth, silky, and light. If you don’t own a food processor, a hand mixer on medium speed for 60 seconds works beautifully.
Fold in half of your reserved bacon crumbles by hand with a rubber spatula you want chunky bacon pieces throughout the filling, not blended into invisibility. If using cheddar cheese, fold that in at this stage too.
Taste critically. Adjust salt, mustard, or lemon juice. The filling should taste bold, smoky, tangy, and rich it should make you want to eat it straight off a spoon. That’s how you know it’s ready.
