If you are looking for big returns for your portfolio in 2025, then check out the ASX 200 growth shares in this article.

As well as being named as buys by brokers, they are being tipped to generate big returns over the next 12 months. Here's what they are saying about them:

Domino's Pizza Enterprises Ltd (ASX: DMP)

The first ASX 200 growth share to consider buying for big returns is Domino's.

It is a pizza chain operator with a large and growing collection of stores across Australia, Asia, and Europe.

The last few years have been very disappointing, but Goldman Sachs thinks that a change is coming. Its analysts note that they "believe that DMP's renewed focus on store unit economics and re-investment to ignite topline growth is rightly placed."

And while there is still significant progress to be made, its analysts "believe that earnings has troughed in FY24 and see a path of improvement through FY25."

Goldman has a buy rating and $39.10 price target on its shares. This implies potential upside of 18% for investors over the next 12 months.

Lovisa Holdings Ltd (ASX: LOV)

Another ASX 200 growth share that could supercharge your investment returns in 2025 is Lovisa.

That's the view of analysts at Morgans, which are very bullish on the fashion jewellery retailer.

And while the broker acknowledges that its "comparable store sales growth should have been better in FY24, it has continued to deliver and will, in our opinion, continue to do so in the years ahead."

In fact, the broker has previously stated its belief that Lovisa is on a "journey to becoming a truly global brand."

Morgans has an add rating and $36.00 price target on its shares. This suggests that its shares could rise 20% from current levels.

Megaport Ltd (ASX: MP1)

Another ASX 200 growth share that analysts think could deliver big returns for investors is leading global provider of elastic interconnection services, Megaport.

Thanks to the cloud computing boom, it has been growing at a strong rate in recent years.

But if you thought its growth was nearing an end, think again! The team at Goldman Sachs believes it can continue for the foreseeable future thanks to "strong structural tailwinds from the adoption of public cloud including multi-cloud usage and the transition towards NaaS technologies."

It is for this reason that Goldman has a buy rating and $10.40 price target on its shares. This implies potential upside of 33% for investors.
