This fast and easy One Pan Rosemary Chicken & Asparagus Dinner is low carb, keto-friendly and full of bright, fresh flavour. If you enjoy tangy, lemon-forward dishes, this recipe will be a hit — the lemon adds a lively, zesty brightness that complements the rosemary and garlic.

Rosemary Chicken Dinner
Rosemary and chicken are a classic pairing. For a lighter spring or summer version — especially when asparagus is in season — lemon and garlic brighten the dish and keep it feeling fresh. This recipe is low in carbs and can easily be adjusted for a higher-fat keto variation by using more olive oil or choosing fattier cuts. Net carbs are low, and the olive oil provides healthy fats.

How to Choose Good Asparagus
- Choose firm, bright green stalks. Medium-thickness stalks are often ideal for texture and cooking time.
- Check the tips — they should be tight and fresh-looking, often green or with a slight purple hue. Tips are the first to go soft.
- Stalks should snap when bent. If they just bend, the asparagus is past peak freshness.
- Pick stalks that look clean and unblemished for best quality and flavor.
Mike’s Tips & Tricks for Rosemary Chicken
- Consider lemon-flavoured olive oil for an extra citrus boost. It’s versatile and delicious on bread with ricotta or in dressings.
- Use a pan with sides (or a sheet pan) so the sauce stays with the chicken while baking.
- Add the asparagus partway through cooking to prevent it from overcooking and becoming limp.
Happy low-carb cooking!
