My uncle swore by this warm and savory dish when the spring greens sprouted. Tossed together with just 4 ingredients, you get incredible smoky flavor in every single bite.

This low carb 4-ingredient hot bacon spinach salad is one of those simple, old-fashioned dishes that feels a little special every time you make it. My uncle swore by this warm and savory salad when the first spring greens popped up in the garden, and I can see why—every bite is smoky, salty, and just a little tangy. The hot bacon and its drippings lightly wilt the spinach, coating the leaves in a glossy vinaigrette that comes together right in the skillet. It’s quick enough for a weeknight but flavorful enough to share with family and friends.

Serve this salad right away while it’s still warm and glossy, either as a light main dish or alongside simple grilled chicken, steak, or pork chops. It pairs nicely with a slice of low-carb bread or a small bowl of tomato soup if you want to stretch it into a fuller meal. I like to pile it onto a big white platter so the deep green spinach and crisp reddish-brown bacon really stand out. A squeeze of extra lemon at the table brightens everything up, and if your family enjoys a little contrast, a few sliced cherry tomatoes or cucumber rounds on the side work well without stealing the spotlight.

Servings: 4

8 cups fresh baby spinach, loosely packed and rinsed dry

Lay the rinsed spinach on a clean kitchen towel or paper towels and pat completely dry. Any extra water will thin the warm bacon dressing, so take a minute to get the leaves as dry as you can, then place the spinach in a large heat-safe salad bowl or on a wide white serving platter.

In a large skillet, add the chopped bacon in a single layer. Turn the heat to medium and cook, stirring occasionally, until the bacon is deep reddish-brown and very crisp, about 8–10 minutes. Adjust the heat as needed so the bacon browns evenly without burning.

Using a slotted spoon, transfer the crispy bacon pieces to a paper towel-lined plate to drain, leaving the hot bacon drippings in the skillet. You’ll want about 3–4 tablespoons of drippings left in the pan for the dressing. If there is significantly more, carefully spoon off the excess into a heatproof container; if there is less, you can top it off with a teaspoon or two of olive oil or butter if desired.

With the skillet still over low heat, whisk the apple cider vinegar and Dijon mustard directly into the hot bacon drippings until the mixture looks glossy and slightly thickened, 30–60 seconds. Taste carefully (it will be hot) and adjust the tang by adding a splash more vinegar if you like a sharper dressing.

Immediately pour the hot bacon vinaigrette evenly over the spinach. The heat will slightly wilt the dark green leaves and give them that shiny, savory coating you’re looking for. Use tongs to gently toss the spinach until every leaf is lightly glossed.

Scatter the crispy bacon pieces over the dressed spinach and toss once more, or leave some bacon on top for a pretty presentation. Serve the salad right away on a large white plate or platter so the rich, earthy colors and glistening texture really show. Enjoy warm for the best flavor and texture.

For picky eaters, you can keep some spinach undressed and let them drizzle a bit of the warm bacon vinaigrette on their own plate so they can control how wilted the leaves get. If someone in your family prefers milder flavors, use a little less vinegar or swap in a white wine vinegar for a softer tang. To add a touch of sweetness without leaving the low carb lane, you can whisk 1/2 teaspoon of granular or liquid low-carb sweetener into the warm dressing. For extra richness, whisk in a teaspoon of butter at the very end of cooking the vinaigrette. If you don’t have baby spinach, torn mature spinach leaves work too—just remove thick stems so the salad still feels tender. You can also swap in baby kale or a mix of spring greens, keeping in mind that sturdier greens will wilt a bit less. For a little crunch, some families like to sprinkle chopped nuts (like pecans or almonds) on top, but that would be an optional fifth ingredient if you’re not strictly sticking to the four-ingredient idea. Food safety tips: Always cook bacon until it is fully crisp and reaches a safe internal temperature; avoid tasting partially cooked bacon. Be careful when adding vinegar and mustard to hot bacon drippings, as the mixture can bubble and release hot steam—keep your face back and use a long-handled whisk or spoon. Let the skillet cool slightly before moving it, and always pour hot drippings away from yourself to avoid splashes. If you have leftover salad, store it in a covered container in the refrigerator and eat within 1 day; the greens will be more wilted but still safe if kept chilled promptly. Reheat gently in a skillet over low heat, or enjoy cold if you don’t mind the softer texture.
