Top 10 Unforgettable 40th Birthday Ideas (That Don’t Involve a Bouncy Castle)

1. Host a Private Chef Dinner at Home (CookinGenie FTW)

This is the Beyoncé of 40th birthday ideas. You book a chef; they roll in with fresh ingredients, whip up a gourmet meal, and clean up like a culinary ninja. You? You just vibe, sip wine and bask in the glory of not lifting a single spatula. CookinGenie makes it ridiculously easy—choose your menu, share your dietary quirks (yes, even vegetarian birthday dinner), and boom, you’re hosting a five-star experience in your living room.

Perfect for unforgettable 40th birthday ideas for her, 40th birthday party ideas for men, and anyone who thinks “adulting” should come with a side of crème brûlée.

2. Weekend Getaway with Your Ride-or-Dies

Rent a cabin in the woods, a beach house, or a bougie Airbnb with a hot tub. Bring your besties, your playlist, and maybe even a chef (CookinGenie chefs are available at many locations; I am just saying). Whether you’re sipping cocktails by the fire or doing face masks in matching robes, this is the kind of 40th birthday celebration idea that feels like a warm hug.

3. Backyard Garden Party with a Twist

Turn your backyard into a Pinterest-worthy paradise. String lights, floral centerpieces, and a chef grilling gourmet sliders while you sip rosé and pretend, you’re on a cooking show. This one’s a hit for 40th birthday themes for her and anyone who loves a good outdoor vibe without the bugs.

4. Wine Tasting Night

You don’t need to be a sommelier to swirl and sip like one. Grab a few bottles (or a dozen), set up tasting stations, and let your chef pair each wine with a bite-sized masterpiece. It’s classy, it’s boozy, and it’s one of those 40-year-old birthday ideas that makes you feel like you’ve got your life together—even if you still Google “how to fold a fitted sheet.”

5. Retro ‘80s or ‘90s Themed Dinner

Neon outfits, cassette tapes, and a playlist that slaps. But the real star? A menu inspired by your childhood favorites—elevated by your chef. Think gourmet mac & cheese, fancy pizza rolls, and desserts that taste like nostalgia. This 40th birthday theme is pure fun with a side of “Remember when?”

6. Spa & Relaxation Day

Massages, facials, cucumber water, and a light, nourishing meal cooked by your personal chef. It’s self-care but make it gourmet. Whether you’re solo or with your squad, this is one of those 40th birthday ideas for women that hits all the right notes—calm, cozy, and delicious.

7. Glam Photoshoot Party

Hire a photographer, get glammed up, and strike a pose. Meanwhile, your chef is plating photogenic bites that look as good as you do. You’ll walk away with killer pics, full bellies, and a party that screams, “I’m 40 and fabulous.” This one’s a top-tier pick for 40th birthday themes for her and anyone who loves a little sparkle.

8. Private Movie Night with Catering

Set up a projector, grab your favorite flicks, and let your chef handle the snacks. We’re talking gourmet popcorn, themed appetizers, and maybe even a dessert inspired by the movie. It’s Netflix, but make it fancy. This is one of those things to do for a 40th birthday that’s low-key but high-impact.

9. Adventure Experience + Dinner

Go zip-lining, hot-air ballooning, or sailing—whatever gets your adrenaline pumping. Then, come home to a warm, chef-prepared meal that feels like a reward for being brave. It’s the perfect combo of thrill and chill and one of the most unforgettable 40th birthday party ideas for him (or her, or them). 

10. Surprise Party with Curated Cuisine

Let your friends do the planning, but make sure they book a chef. Surprise parties are only fun when the food slaps, think-themed dishes, signature cocktails, and a menu that feels like it was made just for you. Whether it’s a rooftop bash or a cozy dinner, this is one of those 40th birthday party ideas that’ll have people talking for years.
