Keto Caesar salad
June 15, 2026 · 3 min read
Caesar salad is closer to keto than most people realise. The classic version — romaine, Parmesan, anchovy dressing — is naturally low carb. The only things that push it over are croutons and bottled dressings that add sugar or flour as thickeners. Remove both and the salad is already there.
Ingredients
- 2 romaine hearts, chopped or left in leaves
- 40g Parmesan, shaved or finely grated
- For the dressing:
- 3 anchovy fillets (or 1 tsp anchovy paste)
- 1 clove garlic, minced
- 2 tbsp mayonnaise
- 1 tbsp lemon juice
- 1 tsp Dijon mustard
- 1 tsp Worcestershire sauce (check label — most are <1g carb per tsp)
- 2 tbsp olive oil
- Salt and black pepper
Steps
- Make the dressing: mash the anchovies and garlic into a paste with a fork, or use a small food processor. Whisk in mayonnaise, lemon juice, Dijon, and Worcestershire. Drizzle in olive oil while whisking until smooth. Season with salt and pepper.
- Toss the romaine with enough dressing to coat — don't drown it.
- Top with shaved Parmesan. Serve immediately.
The dressing
Store-bought Caesar dressing varies widely. Some are clean — a few grams of carbs per serving from Worcestershire and lemon. Others add sugar, modified starches, or maltodextrin and run 4–6g per serving. Check the label before buying, or make the dressing above — it takes three minutes and tastes better.
The anchovy is non-negotiable if you want authentic Caesar flavour. It does not taste fishy in the finished dressing — it dissolves into an umami depth that's the whole point of the sauce. Two or three fillets mashed into a paste is enough for two servings.
Add protein to make it a meal
A Caesar salad is a side or a light lunch on its own. Add protein and it becomes dinner:
| Protein | Notes |
|---|---|
| Grilled chicken breast | The classic; slice thin |
| Seared salmon | 5 minutes per side; rest before slicing |
| Poached shrimp | Simple, quick, goes well with the lemony dressing |
| Bacon lardons | Rendered crispy; replaces the crouton crunch |
| Hard-boiled egg | A half per serving adds protein and richness |
Bacon lardons — small cubes of bacon rendered crispy in a dry pan — are particularly good here. They add the crunch that croutons normally provide, without the carbs.
Common questions
Are Caesar salads keto? The core ingredients — romaine, Parmesan, anchovy dressing — are keto-friendly with about 3g net carbs per serving. The two things that change that are croutons (skip them) and bottled dressings that add sugar or starch (check the label or make your own).
What can I use instead of croutons? Crispy bacon lardons are the best substitute — they add crunch and savory depth. Toasted pumpkin seeds or sunflower seeds also work if you want something lighter. Skip "keto croutons" made from almond flour unless you have tested them; some recipes run higher in carbs than expected.
Is Worcestershire sauce keto? Most brands are fine — about 1g carbs per teaspoon. Lea & Perrins is the standard choice. Use sparingly and it is not an issue.
Can I make the dressing ahead? Yes, up to three days in the fridge. The garlic flavour intensifies over time; some people prefer it made the day before. Keep the romaine separate until serving.
