Bright & Flavorful 3-Ingredient Homemade Raspberry Sauce

I love baking, but sometimes making a full dessert from scratch can feel like a lot, especially when I’m hosting a dinner party or event. If you’re short on time, making just one homemade element is a great way to elevate a store-bought dessert.

Take cheesecake, for example. I love it with raspberry sauce, but making cheesecake from scratch is an all-day endeavor (as in, nothing else is happening that day).

Homemade raspberry sauce, on the other hand, comes together in minutes with just a few ingredients. Drizzle it over a pre-made cheesecake (the frozen one from Trader Joe’s is my favorite), or serve with ice cream or brownies for an easy, impressive dessert.

In this post, I’ll share my go-to 3-ingredient homemade raspberry sauce recipe. It’s bright and flavorful, the perfect low-effort dessert upgrade for your next dinner party.

Ingredients

You only need three ingredients to make this raspberry sauce!

Frozen Raspberries

Start with 12 oz of frozen raspberries. I actually prefer them over fresh — freezing softens the berries, which helps them release more juice and create a smoother sauce.

They’re also way more convenient than fresh raspberries, which tend to be delicate and spoil almost as soon as I bring them home from the store.

You can use fresh raspberries if you prefer, but you may need to simmer the sauce a few extra minutes and add a small splash of water.

Granulated Sugar

Sugar adds sweetness to balance the tartness of the berries. I use just 1/3 cup of granulated sugar here, which makes for a moderately tart sauce that pairs well with sweet desserts like cheesecake.

Fresh Lemon Juice

A teaspoon of fresh lemon juice adds brightness and keeps the sauce from tasting too sweet. I recommend squeezing a real lemon if you can, but bottled juice works fine in a pinch since you only need a little.

Step-by-Step Overview

Here’s a quick look at how this raspberry sauce comes together.

1. Combine ingredients. Add frozen raspberries, sugar, and lemon juice to a saucepan.

2. Simmer. Bring to a boil, then reduce the heat and cook for about 5-10 minutes, stirring occasionally, until the berries break down.

3. Strain (optional). For a smooth sauce, pour through a fine-mesh strainer to remove seeds.

4. Chill and serve. Let cool slightly, then chill before serving.

This sauce yields about 3/4 cup, post-straining, which makes around 6 servings.

Now that you’ve seen how it comes together, here’s the full recipe!

FAQs

See below for answers to common questions about this raspberry sauce.

Can I use fresh raspberries instead of frozen?

Yes! While I prefer frozen raspberries for their convenience and how easily they break down, fresh berries work too. You may just need to simmer the sauce a few extra minutes and add a splash of water. 

Do I have to strain the raspberry seeds out?

No, you don’t have to — but I recommend it if you prefer a smoother, more elegant texture.

How long will this raspberry sauce keep? 

This sauce tastes best within a day or two, but it will keep in the refrigerator for up to a week in a sealed container.

Can I serve this raspberry sauce warm?

Absolutely! Just know that when it’s warm, the sauce will be a little thinner in texture. 

Can I freeze this raspberry sauce?

I haven’t personally tested it, but it should freeze well. Let it cool completely first, then store in an airtight, freezer-safe container for up to three months. Thaw in the fridge overnight before serving.
