Ingredients
Method
- Pat the shrimp dry. Moisture is the enemy of a good sear. Blot both sides with paper towels and season with salt, pepper, and a pinch of paprika.
- Sear the shrimp. Heat 1 tablespoon oil and 1 tablespoon butter in a large skillet over medium-high. Add shrimp in a single layer and cook 1–2 minutes per side until just opaque. Transfer to a plate. Do this in batches if needed.
- Sauté aromatics. Lower heat to medium. Add the remaining oil and butter. Stir in shallot and a pinch of salt. Cook 2–3 minutes until translucent. Add garlic and red pepper flakes; cook 30–45 seconds until fragrant.
- Toast the tomato paste. Stir in tomato paste, paprika, and oregano. Cook 1–2 minutes, stirring, until the paste darkens slightly and smells sweet. This step deepens the flavor.
- Deglaze. Pour in white wine or broth. Scrape up browned bits and simmer 2–3 minutes to reduce by about half.
- Creamy finish. Lower heat to medium-low. Stir in heavy cream and Parmesan. Simmer gently 2–3 minutes until the sauce thickens and looks glossy. Taste and adjust salt and pepper.
- Return the shrimp. Add shrimp and any juices back to the pan. Toss to coat and warm through, 1–2 minutes. Don’t overcook or the shrimp will turn rubbery.
- Brighten. Stir in lemon juice and half the chopped herbs. Taste again and adjust acid, salt, and heat as needed.
- Serve. Spoon over cauliflower rice, zoodles, or greens. Finish with remaining herbs and extra lemon if you like.

How to Make It
- Pat the shrimp dry. Moisture is the enemy of a good sear. Blot both sides with paper towels and season with salt, pepper, and a pinch of paprika.
- Sear the shrimp. Heat 1 tablespoon oil and 1 tablespoon butter in a large skillet over medium-high.
Add shrimp in a single layer and cook 1–2 minutes per side until just opaque. Transfer to a plate. Do this in batches if needed.
- Sauté aromatics. Lower heat to medium.
Add the remaining oil and butter. Stir in shallot and a pinch of salt. Cook 2–3 minutes until translucent.
Add garlic and red pepper flakes; cook 30–45 seconds until fragrant.
- Toast the tomato paste. Stir in tomato paste, paprika, and oregano. Cook 1–2 minutes, stirring, until the paste darkens slightly and smells sweet. This step deepens the flavor.
- Deglaze. Pour in white wine or broth.
Scrape up browned bits and simmer 2–3 minutes to reduce by about half.
- Creamy finish. Lower heat to medium-low. Stir in heavy cream and Parmesan. Simmer gently 2–3 minutes until the sauce thickens and looks glossy.
Taste and adjust salt and pepper.
- Return the shrimp. Add shrimp and any juices back to the pan. Toss to coat and warm through, 1–2 minutes. Don’t overcook or the shrimp will turn rubbery.
- Brighten. Stir in lemon juice and half the chopped herbs.
Taste again and adjust acid, salt, and heat as needed.
- Serve. Spoon over cauliflower rice, zoodles, or greens. Finish with remaining herbs and extra lemon if you like.
Storage Instructions
- Refrigerate: Cool fully, then store in an airtight container for up to 3 days.
- Reheat gently: Warm over low heat on the stove with a splash of cream or broth. Avoid boiling or the shrimp can toughen and the sauce may split.
- Freezing: Not ideal.
Cream sauces can separate, and shrimp can get mealy after thawing. If you must, freeze up to 1 month and reheat slowly.
Why This is Good for You
- Low-carb, high-satiety: The combo of protein and fat helps keep you full without a blood sugar spike.
- Nutrient-dense: Shrimp offers lean protein, selenium, iodine, and B12. Tomato paste brings lycopene and a punch of umami.
- Balanced fats: Butter and olive oil give you flavor and satiety, while Parmesan adds calcium and extra protein.
- Customizable veggies: Pairing with non-starchy sides like zucchini or cauliflower boosts fiber and volume without carbs.
What Not to Do
- Don’t overcook the shrimp. They only need a couple of minutes per side.
Pull them as soon as they turn pink and opaque.
- Don’t skip toasting the tomato paste. Raw paste tastes flat. Toasting unlocks sweetness and depth.
- Don’t boil the cream hard. A gentle simmer keeps the sauce silky and prevents splitting.
- Don’t crowd the pan. Sear shrimp in batches so they brown instead of steam.
- Don’t forget the acid. A squeeze of lemon balances the richness and wakes up the sauce.
Variations You Can Try
- Spicy Calabrian twist: Swap red pepper flakes for chopped Calabrian chiles and add a touch of garlic powder for a bolder kick.
- Rose sauce vibe: Use 1 tablespoon tomato paste plus 1/4 cup sugar-free passata for a pinker sauce (simmer longer to reduce).
- Dairy-light option: Replace half the cream with unsweetened coconut cream. Flavor shifts slightly tropical, but still rich.
- Herb swap: Try dill and chives for a bright, seafood-friendly finish, or basil for an Italian note.
- Extra veg: Stir in sautéed mushrooms, baby spinach, or roasted cherry tomatoes (low-sugar) at the end.
- Smoky bacon base: Start by crisping 2–3 slices of chopped bacon.
Use the rendered fat to sauté aromatics and proceed. Keep salt in check.
- Lemon-garlic heavy: Increase lemon juice to 2–3 tablespoons and add lemon zest for a zippier, lighter profile.
FAQ
Can I use frozen shrimp?
Yes. Thaw them in the fridge overnight or under cold running water, then pat very dry.
Excess moisture will water down your sauce and prevent a good sear.
Is tomato paste okay on keto?
In small amounts, yes. Tomato paste is concentrated, so a couple of tablespoons deliver big flavor with minimal carbs when spread across multiple servings.
What can I use instead of heavy cream?
Full-fat coconut cream works well and keeps it creamy. The taste shifts slightly, so add a bit more lemon and herbs to balance.
Do I need wine?
No.
Low-sodium chicken broth is a fine substitute. If skipping wine, add a tiny splash of apple cider vinegar or extra lemon at the end to mimic that brightness.
How do I prevent a grainy sauce?
Keep heat medium-low once the cream is in, and sprinkle Parmesan in gradually while stirring. Avoid boiling after dairy is added.
What sides keep it keto?
Cauliflower rice, zoodles, spaghetti squash, sautéed kale or spinach, or roasted asparagus all work.
Keep sauces and seasonings simple so the shrimp shines.
Can I make this ahead?
It’s best fresh because shrimp can overcook on reheating. You can prep the aromatics, measure spices, and clean shrimp ahead, then cook in 15 minutes at mealtime.
How spicy is it?
Mild to medium, depending on the red pepper flakes. Start small and adjust.
You can always add heat at the end, but you can’t take it away.
What pan works best?
A large stainless steel or cast-iron skillet gives a better sear and fond for flavor. Nonstick also works but won’t brown as deeply.
How many servings is this?
Typically 4 servings, depending on sides. For heartier appetites or fewer sides, assume 3 generous portions.

Keto Creamy Tomato Garlic Shrimp is the kind of meal that feels indulgent but still fits a low-carb lifestyle.
It brings together familiar flavors—garlic, tomato, cream—in a way that’s quick, versatile, and satisfying. Keep shrimp tender, toast that tomato paste, and finish with lemon for balance.
