Pulling into an In-N-Out in Colorado often means overhearing confident orders that clearly did not come from the printed menu board.

Locals treat the secret menu like second nature, customizing burgers with small tweaks that make a familiar meal feel completely dialed in.

These orders are not about showing off, but about knowing what works best together.

The secret menu allows that flexibility, letting people fine tune their order without complicating things.

You see regulars order quickly, knowing exactly how they want their burger built.

These combinations have spread through word of mouth rather than marketing.

Once you try the right secret menu order, it becomes hard to go back to the default version.

If you want to order like a local and upgrade your next drive through stop, start with these Colorado approved In-N-Out secret menu picks and see which one sticks!

1. Animal Style Burger

You know that moment when the craving hits and only a proper messy burger will do. Slide into the drive-thru and head for the Animal Style Burger, dripping with spread and grilled onions, the kind of order that wins loyalty.

You will find it singing your name at In-N-Out Burger, 4597 N Central Park Blvd, Denver!

Here is the move. Ask for mustard-grilled patties, extra pickles for that briny snap, and grilled onions folded into melted American cheese.

The special spread ties it together with tang and sweetness, giving each bite a little crunch, a little sizzle, and a lot of comfort.

Balance is the secret. The bun stays soft yet toasty, framing the juicy patties while the onions bring deep, caramel richness.

Pickles cut through, keeping things bright so nothing feels heavy, and the spread lingers just long enough to make you chase the next bite.

If you like heat, add chopped chiles and watch the flavor pop. Feeling extra?

Make it a Double Double Animal Style and call it dinner. Or keep it classic and pair with regular fries to let the burger be the main event.

This order thrives on timing, so eat it fresh while the cheese is still gooey and the edges hold their sear. The aroma alone is worth the trip.

You will swipe that last bit of spread with the bun heel and grin.

One tip before you roll out. Ask for light spread if you prefer a crispier bun, or heavy spread if you want sauce to cascade.

Either way, the Animal Style Burger delivers the Denver comfort bite your week deserves.

2. Animal Style Fries

Fries are good, but Animal Style Fries are the move when you want drama. Picture a golden bed of crispy potatoes buried under grilled onions and a sunset of melted cheese, then finished with a zigzag of special spread.

Nab them hot at In-N-Out Burger, 14150 E Alameda Ave, Aurora!

The key is speed. Ask for them well done if you like extra crunch, because the cheese and spread will soften the edges fast.

Those onions add a slow-cooked sweetness that hugs every fry, so each forkful lands with texture, salt, and savory depth.

Want to go bolder? Ask for chopped chiles and extra grilled onions.

The heat sneaks in without crushing the balance, and the fries stay interesting down to the last crispy shard.

There is a technique to eating these. Use a fork to capture onions and cheese in every bite, or fold fries into little scoops.

If you are sharing, order two because nobody wants to fight for the corner with the most cheese pull.

They shine alongside a vanilla shake or a cold soda, giving the spread room to sparkle. If you prefer less sauce, ask for light spread and start modest.

You can always add more.

These fries turn any quick stop into an event. They are indulgent, a little chaotic, and exactly what the moment calls for.

Grab napkins, lean in, and let the onions do the storytelling.

3. Protein Style Burger

You want the burger without the bun, clean and crisp with big flavor. The Protein Style Burger wraps everything in cool lettuce that snaps when you bite, a refreshing contrast to the warm, melty center.

Get yours at In-N-Out Burger, 9171 W Westview Rd, Lone Tree.

The trick is choosing your layers. Add grilled onions for sweetness or raw onions for bite, and ask for extra tomato if you like juicy.

Pickles brighten the whole stack, while spread brings creaminess that plays nicely with the lettuce crunch.

It feels lighter, but not less satisfying. The patty still shines, especially if you go mustard grilled for edge and tang.

Cheese anchors each layer, keeping the stack together so you can eat without the bun getting in the way.

Crave more heft? Make it a Double Double Protein Style, or add chopped chiles for a flicker of heat.

You can even go animal style protein style if you want that signature combo of onions and spread in a lettuce wrap.

Pro tip: ask for your lettuce wrapped tight. It helps keep sauce where it belongs and makes each bite precise.

A side of fries stays optional, but a sparkling soda cuts through the richness like a charm.

This order is perfect for road days, gym days, or just focused days. It is clean, customizable, and fully satisfying.

Lettuce does the heavy lifting, and you still get that In-N-Out soul.

4. 3×3 Triple Triple

Sometimes you need a burger that brings the weight and the wow. The 3×3, or Triple Triple, stacks three juicy patties and three slices of American cheese into a glorious skyscraper bite.

You can grab yours at In-N-Out Burger, 1840 Democracy Point, Colorado Springs!

The best approach is strategy. Ask for mustard-grilled patties to crank up the flavor and choose grilled onions for sweetness that threads through the cheese.

Extra pickles keep the structure lively, and spread stitches it all together without muting the meat.

Take your time with it. The bun stays warm and soft, catching every drip of cheese, while the patties deliver that signature sear.

Each bite lands bold yet balanced, hearty but not muddy, the kind of meal that silences the table for a minute.

If you like crunch, get the fries well done on the side and stack a few inside the burger halfway through. Or keep it classic and let the 3×3 stand alone like a headline act.

A splash of chopped chiles adds spark without nudging out the cheese.

There is pride in finishing a 3×3. It is a clean challenge, not a stunt, and you will feel rewarded rather than wrecked.

The last bites are always the best, where the cheese and onion meet in perfect harmony.

Bring hunger, bring napkins, bring a friend if you want to split. This is the big league of the menu, built for days when appetite shows up loud.

The 3×3 delivers satisfaction on schedule and leaves you smiling.

5. 4×4 Quad Quad

Claim one at In-N-Out Burger, 111 E 136th Ave, Thornton!

Approach with a plan. Ask for extra lettuce and tomato to keep freshness in the mix, and go grilled onions to blend sweetness into the cheese.

Mustard-grilled patties boost that seared edge, and light spread can help maintain structure if you want fewer drips.

The first bite is a show. You will feel the heat, the melt, the crunch of lettuce, and the clean salt of beef in one rush.

Despite the height, it stays cohesive, especially if you eat slowly and keep the wrapper snug.

Want a twist? Add chopped chiles for sparkle, or swap in raw onion for sharp bite and extra lift.

Fries on the side let you control the richness, and a fountain drink resets the palate between glorious mouthfuls.

The 4×4 is not everyday food, and that is what makes it special. It is the kind of order you remember, a mini milestone worth a quick detour.

Save space, savor the middle, and enjoy the cheese-drenched finale.

When the last bite lands, you will know it was the right call. Big appetite, big flavor, big grin.

That is the Quad Quad, delivering a victory lap in burger form.

6. Flying Dutchman

Sometimes simple is strongest, and the Flying Dutchman proves it in two patties and two slices of cheese. No bun, no lettuce, just molten, savory focus.

Pick one up at In-N-Out Burger, 150 S Wadsworth Blvd, Lakewood!

This is perfect when you want protein without distractions. Ask for mustard-grilled patties for a tangy edge, and consider grilled onions on the side if you miss a touch of sweetness.

The cheese melts right into the crust, forming a savory blanket that hugs every bite.

It eats neat with a fork, or you can fold the wrapper and go handheld. Each mouthful feels concentrated, like the best part of a burger made the main event.

Salt, sear, and melt come through in clean layers.

Looking to customize? Add chopped chiles for a flicker of heat, or slide tomato slices on top for a bright counterpoint.

If you want a little texture, order well-done fries and alternate bites, crisp then creamy.

This pick travels well, too. It stays warm and melty without the bun getting soggy, making it a tidy option on the go.

Keto minded or not, the Dutchman respects your time and appetite.

There is a quiet joy in how direct it is. No fluff, no filler, just the flavor you came for.

Craving comfort without the meat? The Grilled Cheese brings toasted bun warmth and bubbly American cheese with all the classic fixings.

Order it fresh at In-N-Out Burger, 1450 Fall River Dr, Loveland.

This sandwich is all about texture. The bun carries a light toast, the cheese oozes, and crisp lettuce plus tomato keep things refreshing.

Add grilled onions for sweetness or raw for extra bite, then let the spread tie everything together.

It is simple, but not plain. Cheese becomes the star, buttery and rich, especially if you ask for extra.

A little pickle lifts the profile and keeps each bite lively.

Want more zip? Ask for chopped chiles or go mustard grilled on the inside of the bun for subtle tang.

Pair with fries well done if you like more crunch, or regular fries for a softer dance with the cheese.

There is nostalgia in every bite, the kind that feels like an after-school snack upgraded for grown appetites. It is quick, satisfying, and friendly to all kinds of days.

You can even go double cheese if you are chasing that extra melt.

If you are sharing a table, this is the easy crowd pleaser. It travels well, tastes great hot, and still charms warm.

The Grilled Cheese is your cozy lane, mellow and marvelous in equal measure.

When you cannot choose a flavor, pick all three. The Neapolitan Shake blends chocolate, vanilla, and strawberry into one creamy sip that moves from nostalgic to luxurious in seconds.

Grab yours at In-N-Out Burger, 3860 Eagle Boulevard, Brighton.

The trick is the swirl. Ask for a balanced pour so each flavor shows up, then give it a gentle roll before the first sip.

Chocolate leads, vanilla smooths, and strawberry lifts, creating a rhythm that stays interesting from top to bottom.

It pairs beautifully with salty bites. Sip between fries or a burger and notice how the shake resets your palate.

Every return to the straw feels like a new little treat.

Want it thicker? Ask for extra thick blend and let it sit one minute so the texture hits perfect spoon territory.

Prefer more fruit? Request a strawberry heavy swirl and lean into the tart sweetness.

This shake is a mood lifter on long drives and quick errands alike. The palm tree cup feels classic in your hand, and the first cold hit is instant happiness.

It is dessert without formality, just joy on standby.

Take it slow, savor the drift from chocolate to strawberry, and chase the vanilla finish. By the last sip, you will be planning the next one.

The Neapolitan is the easiest win on the menu, every single time.

9. Roadkill Fries

Ready for the secret within the secret. Roadkill Fries stack Animal Style Fries and a Flying Dutchman into one outrageous fork feast, the definition of extra in the best way.

Hunt them down at In-N-Out Burger, 735 Harvest Moon Dr, Longmont!

Start with well-done fries so they hold under the weight. Ask for grilled onions heavy and cheese fully melted, then add the Dutchman right on top.

The spread weaves through, landing each bite creamy, salty, and deeply savory.

It is shareable, but you might not want to. The top layer gives you beef and cheese, while the bottom brings tangy, saucy potatoes that soak up every drip.

Fork your way from edge to center and watch the textures shift.

Want a spark? Add chopped chiles and an extra packet of spread on the side.

Mix as you go, adjusting heat and richness until it sings for you.
