A great margarita doesn't need a mix. It doesn't need triple sec. It doesn't need a bucket of sugar. All it needs is fresh lime juice, good tequila, and a touch of blue agave nectar to balance the tartness. The result is cleaner, brighter, and more refreshing than anything that comes out of a bottle — and once you taste it, you'll never go back to the premixed stuff.

This is my go-to recipe. Three ingredients, five minutes, and it works just as well for a quiet Tuesday night as it does for a backyard full of guests.

Ingredients for Dad's Skinny Margarita — Kirkland Tequila Blanco, organic blue agave, fresh limes, and a citrus juicer
The lineup: Kirkland Tequila Blanco · Organic Blue Agave · Fresh Limes · That's it.

The Recipe

Dad's Skinny Margarita
Fresh · Clean · No Mix · Serves 1
  • 2 oz Tequila Blanco Kirkland Tequila Blanco (Costco) is excellent quality for the price
  • 1 oz Fresh Lime Juice Juice of approximately 1–1½ limes · fresh squeezed, no exceptions
  • ½ tsp Blue Agave Nectar Kirkland Organic Blue Agave · adjust to your sweetness preference
  • Ice Plenty of it — fill your glass and shaker
  • Optional Salt or Tajín for the rim Classic salt or Tajín adds a nice counterpoint to the tart lime
  1. 1Rim the glass (optional): Run a lime wedge around the rim of your glass, then press it into a plate of salt or Tajín. Fill the glass with ice and set aside.
  2. 2Juice the limes: Squeeze fresh limes until you have 1 oz of juice — about 1 to 1½ limes depending on size. Fresh juice is non-negotiable here. Bottled lime juice tastes flat and bitter.
  3. 3Combine in a shaker: Add the tequila, fresh lime juice, and blue agave nectar to a cocktail shaker filled with ice.
  4. 4Shake hard for 15 seconds: You want it well-chilled and slightly diluted — this is what makes it smooth and balanced.
  5. 5Strain into your glass over fresh ice. Garnish with a lime wedge. Drink immediately.
The Most Important Rule

"Fresh lime juice. Every single time. I know it's more work than squeezing from a bottle. Do it anyway. The difference between fresh-squeezed lime and bottled is the entire difference between a great margarita and a mediocre one. Your citrus juicer pays for itself the first weekend you use it."

Why These Three Ingredients?

🥃
Kirkland Tequila Blanco
Costco · 100% Blue Agave
Kirkland's Tequila Blanco is made from 100% blue agave and consistently ranks with bottles costing twice as much. Clean, slightly sweet, with a bright agave flavor that's ideal for cocktails. At Costco prices, it's the best value in tequila, full stop.
🍋
Fresh Limes
Fresh Squeezed · No Substitutes
The backbone of the drink. Fresh lime juice is bright, aromatic, and slightly floral. Bottled lime juice is pasteurized and preservative-laden — it tastes flat and metallic by comparison. Buy limes in bulk (Costco nets are perfect) and squeeze to order.
🌵
Blue Agave Nectar
Organic · Low Glycemic
Agave nectar dissolves instantly in cold liquids (unlike simple syrup, which needs to be made warm) and has a clean, neutral sweetness with a subtle floral note that complements tequila naturally — they come from the same plant. Start with ½ tsp and adjust to taste.

Calorie Count

One of the best things about making a margarita from scratch — no mix, no triple sec, no added sugar — is knowing exactly what's in it. Here's the full breakdown for one serving of this recipe:

Calorie Breakdown — Per Drink
Based on standard recipe · 1 serving
Ingredient Amount Calories
Tequila Blanco (80 proof) 2 oz 128
Fresh Lime Juice 1 oz 8
Blue Agave Nectar ½ tsp 10
Total ~146

Compare that to a typical bar margarita: A standard restaurant margarita made with sweet-and-sour mix and triple sec typically runs 300–500+ calories per drink. Skipping the mix and the orange liqueur cuts the calorie count roughly in half — without sacrificing any of the flavor.

Why Skip Triple Sec?

Traditional margaritas use triple sec or Cointreau — an orange liqueur — as the third ingredient. Skipping it keeps the drink lighter (fewer calories, lower alcohol), cleaner (no artificial orange flavor), and more lime-forward. The agave nectar provides all the sweetness you need without the syrupy quality of orange liqueur. If you want a hint of orange, a tiny dash of orange bitters does the job beautifully without the weight of a full liqueur.

Batch Tip for Parties

For large batches, pre-juice all your limes and mix the tequila, lime juice, and agave in a pitcher ahead of time (without ice). Refrigerate the base until ready to serve, then shake or stir each drink over ice to order — or pour the batch over a large ice-filled pitcher and stir well. Pre-mixing more than a couple hours ahead can slightly dull the lime's brightness, so batch the day of.

Variations Worth Trying

Spicy Skinny Margarita
Add: 2–3 slices fresh jalapeño
Muddle 2–3 thin jalapeño slices in the shaker before adding ice and other ingredients. Strain out the pepper before pouring. The heat from the jalapeño plays brilliantly against the tart lime. Addictive.
Tajín Rim Margarita
Swap: Salt for Tajín on the rim
Tajín (chili-lime seasoning) on the rim instead of salt adds a spicy, citrusy punch to every sip. It's become my default — the complexity it adds to the first sip of each drink is unmatched.
Frozen Skinny Margarita
Blend with 1 cup ice
Same recipe, but blend everything (tequila, lime, agave, and a full cup of ice) in a blender until smooth. Perfect for summer afternoons. Add half a frozen banana for a creamier texture without altering the flavor much.
Watermelon Skinny Margarita
Add: 2 oz fresh watermelon juice
Blend fresh watermelon and strain out the pulp to get pure watermelon juice. Add 2 oz to the standard recipe, reduce lime juice slightly to ¾ oz. Stunning color, incredibly refreshing for summer parties.
Skinny Paloma Twist
Swap: Top with grapefruit sparkling water
Make the base recipe, pour over ice, and top with 2–3 oz of grapefruit sparkling water (Topo Chico grapefruit is excellent). It lightens the drink and adds a beautiful pink hue with bitter citrus notes.
Smoky Skinny Margarita
Swap: 1 oz tequila for mezcal
Replace half the tequila (1 oz) with a mezcal of your choice. The smoky, earthy quality of mezcal adds incredible depth to the lime and agave. A more complex, sophisticated drink — not for everyone, perfect for some.
Dad's Final Word

"Keep a bag of limes, a bottle of good blanco, and some blue agave in the kitchen at all times. When someone drops by, you're twenty seconds away from offering them a drink that's better than anything at a bar. That's the kind of hospitality that makes people want to come back."
