What Makes a Good Keto Lunch?

To stay in ketosis, your lunch should:

• Be low in net carbs (usually under 10–15g)
• Include moderate protein (like chicken, beef, tuna, or eggs)
• Include healthy fats (like olive oil, avocado, cheese, or butter)

What to avoid: Bread, rice, pasta, tortillas, sweetened dressings or sauces, and most takeout unless you customize it.

According to Cleveland Clinic, keto meals should center around whole foods like meat, eggs, low-carb veggies, and healthy fats.

Easy Hot Keto Lunches

When you have a few extra minutes, these simple hot meals are incredibly satisfying.

1. Ground Beef and Veggie Skillet

This one-pan meal has become a weekly staple in my house. Rich, savory, and ready in minutes.

Ingredients:

• 6 oz ground beef (80/20 for best flavor)
• 1 cup cauliflower rice (fresh or frozen)
• 1 tbsp olive oil
• 2 cloves garlic, minced
• ½ tsp paprika
• Salt and pepper to taste
• ¼ cup shredded cheddar cheese

Instructions:

1. Heat olive oil in a large skillet over medium-high heat.
2. Add ground beef and break apart. Cook 5-6 minutes until browned.
3. Add garlic and paprika, stir for 30 seconds.
4. Add cauliflower rice, stir and cook 3-4 minutes until tender.
5. Season with salt and pepper. Top with cheese and serve.

Prep time: 5 minutes | Cook time: 12 minutes

2. Chicken Caesar Bowl (No Croutons)

All the creamy Caesar flavor without the carbs. You won’t miss the croutons.

Ingredients:

• 5 oz grilled chicken breast or thigh, sliced
• 3 cups chopped romaine lettuce
• 2 tbsp shaved Parmesan cheese
• 2 tbsp Caesar dressing (check for no added sugar—Primal Kitchen is a good option)
• Optional: 2 anchovy fillets, crispy bacon bits

Instructions:

1. Chop romaine and place in a large bowl.
2. Top with sliced chicken.
3. Drizzle with Caesar dressing and toss to coat.
4. Top with Parmesan and any optional additions.

Prep time: 8 minutes | Cook time: 0 minutes (if using pre-cooked chicken)

3. Keto Quesadilla (No Tortilla)

The secret? Cheese becomes the “tortilla” when you crisp it in a pan. Trust me on this one.

• Sauté cheese in a pan until crisp
• Add cooked meat or avocado inside
• Fold like a quesadilla

Net carbs: 2g

Diet Doctor recommends simple skillet meals and bowls as long as ingredients are low in carbs and high in fat.

4. BLT Lettuce Wraps

All the flavors of a classic BLT, wrapped in crispy lettuce instead of bread.

• Crispy bacon
• Sturdy romaine leaves
• Fresh tomato slices (just a few)
• Creamy mayo

Net carbs: 3g

Meal Prep Keto Lunch Ideas

Make a batch on Sunday and eat all week. This is where keto lunch gets really easy.

• Egg salad or tuna salad — keeps 4-5 days in the fridge
• Chicken thighs baked with olive oil and herbs — versatile and delicious
• Cauliflower mash with ground sausage — comfort food that reheats beautifully
• Zucchini noodles with garlic butter shrimp — light but filling
• Keto chili (no beans) — freezes well for even longer storage

Budget-Friendly Keto Lunches (Under $3 Per Meal)

You don’t need fancy ingredients. Simple proteins, veggies, and fats go a long way.

Office and On-the-Go Tips

Pack smart: Use a thermos for soups or hot meals

Portion control: Pack in bento boxes with clear sections

Skip the bread: Use lettuce or cheese wraps instead

BYOD (Bring Your Own Dressing): Store-bought ones often have hidden sugar

Batch and freeze: Freeze leftovers in single portions for grab-and-go convenience

Leftover Lunch Wins

Here’s the thing—one of the easiest keto lunches is dinner from last night.

Reheat, repurpose, or eat cold—leftover chicken, beef, or roasted veggies all work. I do this at least three times a week, and it saves both time and money.

Some of our meal plans include dinner-to-lunch transitions. Try our Beginner Keto Meal Plan if you’re just getting started.

Should You Skip Lunch?

If you’re doing intermittent fasting (IF), you might skip lunch and eat two meals a day. That’s okay, but not required.

If you’re hungry at lunch, eat. Skipping meals when you’re new to keto can backfire and lead to overeating later.

Mayo Clinic says fasting isn’t for everyone and shouldn’t leave you tired or dizzy.

Frequently Asked Questions

How many carbs should a keto lunch have?

Aim for under 10–15g net carbs. This gives you room for carbs at breakfast and dinner while staying within your daily 20–50g total.

Can I eat the same lunch every day?

Absolutely. Many successful keto eaters repeat their favorites. It simplifies meal prep and shopping. If you enjoy variety, batch prep two or three options each week.

What about eating out for lunch?

Look for grilled proteins, ask for extra veggies instead of starchy sides, and skip the bread. Most restaurants can accommodate keto requests if you ask.

How do I keep lunch fresh until I eat it?

An insulated lunch bag with an ice pack keeps cold foods safe. For hot foods, preheat a thermos with boiling water before adding your meal.
